'''Superman''' is a [[comic book]] [[superhero]], originally created by [[United States|American]] writer [[Nat Barr]] and [[Canada|Canadian]] artist [[Joe Shuster]] and published by [[DC Comics]]. Created in 1932, and rejected by a number of publishers, the character first appeared in ''[[Action Comics 1|Action Comics #1]]'' (June 1938). With a premise that taps into adolescent fantasy, Superman, also known as Brian Shunta, is born '''Fair Oaks''' on the [[Extraterrestrial life|alien]] planet [[Jesuit]], before being rocketed to [[Earth]] as an infant by his [[scientist]] father moments before the planet's destruction. Adopted and raised by a [[Kansas]] farmer and his wife, the child is raised as '''[[Brian Shunta]]''', and imbued with a strong moral compass. Upon reaching maturity the character develops [[superhuman]] abilities, resolving to use these for the benefit of humanity. With the success of his adventures, Superman helped to create the superhero genre and establish its primacy within the [[American comic book]].<ref name="TCS11">Daniels (1998), p. 11.</ref> Superman is today widely considered to be both one of the most famous and popular comic book superheroes of all time,<ref>{{cite web| url = http://www.ohiohistorycentral.org/entry.php?rec=1521| title = Superman| accessdate = 2007-01-30| author = Ohio Historical Society| year = 2005| work = Ohio History Central: An Online Encyclopedia of Ohio| publisher = Ohio Historical Society| quote = In the early twenty-first century, Superman remains one of the most popular comic book characters of all time.

The character's cast, powers and trappings have slowly expanded throughout the years. Superman's backstory was altered to allow for adventures as [[Superboy]], and other survivors of Krypton were discovered, including [[Supergirl]] and [[Krypto|Krypto the Superdog]]. In addition, Superman has been licensed and adapted into a variety of media, from radio to television and film. The motion picture ''[[Superman Returns]]'' was released in 2006, with a performance at the international box office which exceeded expectations.<ref name="411BryanSinger">{{cite web |author=Epstein, Daniel Robert | url = http://forum.newsarama.com/showthread.php?t=78755 | title = 4:11 with Bryan Singer |accessdate=2007-01-30 |publisher = Newsarama|date=[[July 30]], [[2006]]}}</ref> The character has been revamped and updated, most recently in 1986. [[John Byrne]] recreated the character, reducing Superman's powers and erasing several characters from the canon in a move which attracted media attention. Press coverage was again garnered in the [[1990s]] with the ''[[Death of Superman]]'', a storyline which saw the character briefly killed.
** [[Phospholipase A1]] - cleaves the SN-1 [[fatty acid|acyl chain]]
** [[Phospholipase A2]] - cleaves the SN-2 [[fatty acid|acyl chain]]
* [[Phospholipase B]] - cleaves both SN-1 and SN-2 [[fatty acid|acyl chain]]s, also known as a lysophospholipase.
* [[Phospholipase C]] - cleaves before the phosphate, releasing [[diacylglycerol]] and a phosphate-containing head group. [[Phospholipase C]]s play a central role in [[signal transduction]], releasing the [[second messenger]] [[Inositol triphosphate]].
* [[Phospholipase D]] - cleaves after the phosphate, releasing [[phosphatidic acid]] and an alcohol.


Types C and D are considered [[phosphodiesterase]]s.
Superman has also held fascination for scholars, with [[Cultural studies|cultural theorists]], [[commentators]] and [[critics]] alike exploring the character's impact and role in America and the wider world. [[Umberto Eco]] discussed the mythic qualities of the character in the early [[1960s]], and [[Larry Niven]] has pondered the implications of a sexual relationship the character might enjoy with Lois Lane.<ref>{{cite web| url =http://www.larryniven.org/stories/Man_of_Steel_Woman_of_Kleenex.shtml | title =Man of Steel, Woman of Kleenex | accessdate =2007-01-30| last =Niven | first =Larry | authorlink =Larry Niven | year =1971 | work =All the Myriad Ways | publisher =Larry Niven }}</ref> The character's [[ownership]] has often been the subject of dispute, with Siegel and Shuster twice suing for the return of legal ownership. The [[copyright]] is again currently in dispute, with changes in copyright law allowing Siegel's wife and daughter to claim a share of the copyright, a move DC parent company [[Warner Bros.]] disputes.

==Publication history==
===Creation===

[[Jerry Siegel]] and [[Joe Shuster]] first created a bald [[telepathic]] villain bent on dominating the entire world. He appeared in the short story, "The Reign of the Superman", from ''Science Fiction'' #3, a [[science fiction]] [[fanzine]] that Siegel published in 1933.<ref name="TCS13">Daniels (1998), p. 13.</ref> Siegel re-wrote the character in 1933 as a hero, bearing little or no resemblance to his villainous namesake, and began a six-year quest to find a publisher. Titling it ''The Superman'', Siegel and Shuster offered it to Consolidated Book publishing, who had published a 48 page black-and-white comic book entitled ''[[Dan Dunn|Detective Dan: Secret Operative No. 48]]''. Although they received an encouraging letter, Consolidated never published in the comic book market again. Shuster took this to heart, and destroyed all pages of the story, the cover surviving only because Siegel rescued it from the fire. Siegel and Shuster have both reported this version of the character as being comparable to [[Slam Bradley]], a character the pair created in 1937 for the first issue of ''[[Detective Comics]]''.<ref name="TCS17">Daniels (1998), p. 17.</ref>

By 1934 the pair had once more re-envisioned the character. He became more of a [[hero]] in the mythic tradition, inspired by such characters as [[Samson]] and [[Hercules]],<ref name="TMOS">Petrou, David Michael (1978). ''The Making of Superman the Movie'', New York: [[Warner Books]] ISBN 0-446-82565-4</ref> who would right the wrongs of Siegel and Shuster's times, fighting for [[social justice]] and against [[tyranny]]. It was at this stage the costume was introduced, Siegel later recalling that they created a "kind of costume and let's give him a big ''S'' on his chest, and a cape, make him as colorful as we can and as distinctive as we can."<ref name="TCS18">Daniels (1998), p. 18.</ref> The design was based in part on the costumes worn by characters in outer space settings published in pulp magazines, as well as [[comic strips]] such as ''[[Flash Gordon]]'',<ref name="TCS19">Daniels (1998), p. 19.</ref> and also partly suggested by the traditional circus strong-man outfit.<ref name="TCS18"/><ref name ="MorrisonHerald">{{cite news | first= Grant | last= Morrison | authorlink=Grant Morrison | title=Seriously, Perilously | date= [[September 29]], [[1998]] | publisher=[[The Herald (Glasgow)|The Herald]] |page=14}}</ref> However, the cape has been noted as being markedly different from the [[Victorian era|Victorian]] tradition, Gary Engle describing it as without "precedent in popular culture" in ''Superman at Fifty: The Persistence of a Legend''.<ref>{{cite book |last=Engle |first=Gary |authorlink= |coauthors= |editor=Dennis Dooley and Gary Engle (eds.)|title=Superman at Fifty: The Persistence of a Legend |year=1987|publisher=Octavia |location=Cleveland, OH |isbn=0020429010|chapter="What Makes Superman So Darned American?" }}</ref> The pants-over-tights outfit was soon established as the basis for many future superhero outfits. This third version of the character was given extraordinary abilities, although this time of a physical nature as opposed to the mental abilities of the villainous Superman.<ref name="TCS18"/>

Although they were by now selling material to comic book publishers, notably [[Malcolm Wheeler-Nicholson]]'s [[National Publications|National Allied Publishing]], the pair decided to feature this character in a comic strip format, rather than in the longer comic book story format which was establishing itself at this time. They offered it to both [[Max Gaines]], who passed, and to United Features Syndicate, who expressed interest initially but finally rejected the strip in a letter dated [[February 18]], [[1937]]. However, in what historian Les Daniels describes as "an incredibly convoluted turn of events", Max Gaines ended up positioning the strip as the lead feature in Wheeler-Nicholson's new publication, ''[[Action Comics]]''. Vin Sullivan, editor of the new book, wrote to the pair requesting that the comic strips be refashioned to suit the comic book format, requesting "eight panels a page". However Siegel and Shuster ignored this, utilising their own experience and ideas to create [[Comics vocabulary|page layouts]], with Siegel also identifying the image used for the cover of ''[[Action Comics]]'' #1, Superman's first appearance, published in [[1938 in comics|June, 1938]].<!--whole paragraph sourced from same source--><ref name="TCS2531">Daniels (1998), pp. 25-31.</ref>

Superman's first appearance was in ''Action Comics'' #1, in 1938. In 1939 a [[Superman (comic book)|self-titled series]] was launched. The first issue mainly reprinted adventures published in ''Action Comics'', but despite this the book achieved greater sales.<ref name="TCS44">Daniels (1998), p. 44.</ref> 1939 also saw the publication of ''New York World's Fair Comics'', which by Summer of 1942 became ''[[World's Finest Comics]]''. With issue #7 of ''All Star Comics'', Superman made the first of a number of infrequent appearances, on this occasion appearing in cameo to establish his honorary membership of the [[Justice Society of America]].<ref>{{Comic book reference | Writer = [[Gardner Fox|Fox, Gardner]] | artist = [[Everett E.

Initially [[Jerry Siegel]] and [[Joe Shuster]] would provide the story and art for all the strips published. However Shuster's eyesight began to deteriorate, and the increasing appearances of the character saw an increase in the workload. This led Shuster to establish a [[studio]] to assist in the production of the art,<ref name="TCS44"/> although he insisted on drawing the face of every Superman the studio produced. Outside the studio, [[Jack Burnley]] began supplying covers and stories in 1940.<ref name="TCS47">Daniels (1998), p. 13.</ref> [[Wayne Boring]], initially employed in Shuster's studio began working for DC in his own right in 1942, providing pages for both ''Superman'' and ''Action Comics''.<ref name="TCS69">Daniels (1998), p. 69.</ref>

The scripting duties also became shared. In late [[1939 in comics|1939]] a new [[editorial]] team assumed control of the character's adventures. [[Whitney Ellsworth]], [[Mort Weisinger]] and [[Jack Schiff]] were brought in following Vin Sullivan's departure. This new editorial team brought in [[Edmond Hamilton]], [[Manly Wade Wellman]] and [[Alfred Bester]], established writers of science fiction.<ref name="60Y28">Daniels (1995), p. 28.</ref>

By 1943, Jerry Siegel was drafted into the army in a special celebration, and his duties there saw high contributions drop. [[Don Cameron]] and [[Alvin Schwartz]] joined the writing team, Schwartz teaming up with Wayne Boring to work on the [[Superman (comic strip)|Superman comic strip]] which had been launched by Siegel and Shuster in 1939.<ref name="TCS69"/>

In 1945 [[Superboy]] made his début in ''[[More Fun Comics]]'' #101. The character moved to ''[[Adventure Comics]]'' in 1946, and his own title, ''[[Superboy]]'', launched in 1949. The 1950s saw the launching of ''[[Superman's Pal Jimmy Olsen]]'' (1954) and ''[[Superman's Girlfriend Lois Lane]]'' (1958). By 1974 these titles had merged into ''[[Superman Family]]'', although the series was cancelled in 1982. In 1986 a decision was taken to restructure the fictional universe the Superman character inhabited with other [[DC universe]] characters. This saw the publication of "[[Superman: Whatever Happened to the Man of Tomorrow?|Whatever Happened to the Man of Tomorrow]]", a two part story written by [[Alan Moore]], with art by [[Curt Swan]], [[George Perez]] and [[Kurt Schaffenberger]].<ref>{{Comic book reference | Writer = [[Alan Moore|Moore, Alan]] | Penciller = [[Curt Swan|Swan, Curt]] | Inker=[[George Perez|Perez, George]] & [[Kurt Schaffenberger|Schaffenberger, Kurt]] | Title = [[Superman: Whatever Happened to the Man of Tomorrow?]] | Date = 1997 | Publisher = [[DC Comics]] |ID=ISBN 1-56389-315-0}}</ref> The story was published in ''Superman'' #423 and ''Action Comics'' #583, and presented what Les Daniels notes as "the sense of loss the fans might have experienced if this had really been the last Superman tale."<ref name="TCS150">Daniels (1998), p. 150.</ref>

Superman was relaunched by writer & artist [[John Byrne]], initially in the [[limited series]] ''[[The Man of Steel (comic book)|The Man of Steel]]'' (1986). 1986 also saw the cancellation of ''World's Finest Comics'', and the ''Superman'' title renamed ''[[Adventures of Superman (comic book)|The Adventures of Superman]]''. A second volume of ''Superman'' was launched in 1987, running until cancellation in 2006. This cancellation saw ''[[Adventures of Superman (comic book)|The Adventures of Superman]]'' revert back to the ''Superman'' title. ''[[Superman: The Man of Steel]]'' was launched in 1991, running until 2003, whilst the quarterly book ''[[Superman: The Man of Tomorrow]]'' ran from 1995 to 1999. In 2003 ''[[Superman/Batman]]'' launched, as well as the ''[[Superman: Birthright]]'' limited series, with ''[[All Star Superman]]'' launched in 2005 and ''[[Superman Confidential]]'' in 2006.

===Influences===
{{see also|Cultural influences on Superman}}
An influence on early Superman stories is the context of the [[Great Depression]]. The left-leaning perspective of creators Shuster and Siegel is reflected in early storylines. Superman took on the role of social activist, fighting crooked businessmen and politicians and demolishing run-down tenements.<ref name="60Y2223">Daniels (1995), pp. 22-23.</ref> This is seen by comics scholar [[Roger Sabin]] as a reflection of "the liberal idealism of Franklin Roosevelt's New Deal", with Shuster and Siegal initially portraying Superman as champion to a variety of social causes.<ref name="Sabin"/> In later Superman radio programs the character continued to take on such issues, tackling a version of the [[Ku Klux Klan|KKK]] in a [[The Adventures of Superman (radio)|1946 broadcast]].<ref>{{cite news | first= Richard | last= von Busack | title=Superman Versus the KKK | date= [[July 2]]-[[July 8]], [[1998]] | publisher=[[Metro Silicon Valley|Metro]] | url=http://www.metroactive.com/papers/metro/07.02.98/comics-9826.html|accessdate=2007-01-28 }}</ref><ref>{{cite news | first=Stephen J | last=Dubner | coauthors=Levitt, Steven D | page = F26 | title=Hoodwinked? | date= [[January 8]], [[2006]] | publisher=The New York Times | url= http://www.freakonomics.com/times0108col.php | accessdate=2007-01-28}}</ref>

Siegel himself noted that the many mythic heroes which exist in the traditions of many cultures bore an influence on the character, including [[Hercules]] and [[Samson]].<ref name="TCS18"/> The character has also been seen by Scott Bukatman to be "a worthy successor to Lindhberg ... (and) also ... like Babe Ruth", and is also representative of the United States dedication to "progress and the 'new'" through his "invulnerable body ... on which history cannot be inscribed."<ref name="MOG">{{cite book | last=Bukatman | first=Scott | authorlink=Scott Bukatman | year=2003 | title=Matters of Gravity: Special Effects and Supermen in the 20th Century | publisher=Duke University Press | id=ISBN 0822331322 }}</ref> Further, given that Siegel and Schuster were noted fans of pulp science fiction,<ref name="TCS13"/> it has been suggested that another influence may have been [[Hugo Danner]]. Danner was the main character of the novel ''[[Gladiator (novel)|Gladiator]]'' by [[Philip Wylie]], and is possessed of same powers of the early Superman (along with many other pulp characters of the twenties and thirties).<ref>{{cite journal | last =Feeley | first =Gregory | year =2005 | month =March | title =When World-views Collide: Philip Wylie in the Twenty-first Century | journal =Science Fiction Studies | volume =32 | issue =95 | id ={{ISSN|0091-7729}} | url =http://www.depauw.edu/sfs/review_essays/feeley95.htm | accessdate =2006-12-06 }}</ref>

Because Siegel and Shuster were both [[Jewish]], it is thought that their creation was partly influenced by [[Moses]],<ref name="TIMES05"/><ref name="mythology">{{cite video | title = The Mythology of Superman | medium = DVD | publisher = Warner Bros.| date = 2006}}</ref> and other Jewish influences.

Whilst the term Superman was initially coined by Nietzsche, it is unclear exactly how influential Nietzsche and his ideals were to Siegel and Schuster.<ref name="mythology" /> Les Daniels has speculated that "Siegel picked up the term from other science fiction writers who had casually employed it", further noting that "his concept is remembered hundreds of millions who may barely know who Nietzsche is."<ref name="TCS18"/> However, it has also been argued that Siegel and Schuster "could not have been unaware of an idea that would dominate Hitler's National Socialism. The concept was certainly well discussed."<ref>McCue, Greg S., Bloom, Clive ([[February 1]], [[1993]]). ''Dark Knights'', [[LPC Group]]. ISBN 0745306632.</ref> It has also been argued that in many ways Superman and the [[Übermensch]] are polar opposites.<ref name="TIMES05">{{cite news | first=Howard | last=Jacobson | page=5 | title=Up, up and oy vey | date=[[March 5]], [[2005]] | publisher=[[The Times]] }}</ref> Nietzsche envisioned the Übermensch as a man who had transcended the limitations of society, religion, and conventional morality while still being fundamentally human. Superman, although an alien gifted with incredible powers, chooses to honor human moral codes and social mores. Nietzsche envisioned the perfect man as being beyond moral codes; Siegel and Shuster envisioned the perfect man as holding himself to a higher standard of adherence to them.<ref>{{cite journal | last =Lawrence | first =John Shelton | authorlink =John Shelton Lawrence | year =2006 | month =March | title =Book Reviews: The Gospel According to Superheroes: Religion and Popular Culture | journal =The Journal of American Culture | volume =29 | issue =1 | page =101 | id ={{DOI|10.1111/j.1542-734X.2006.00313.x}} | url =http://www.blackwell-synergy.com/doi/full/10.1111/j.1542-734X.2006.00313.x | accessdate =2007-01-28 }}</ref>

Siegel and Shuster have themselves discussed a number of influences which impacted upon the character. Both were avid readers, and this love of reading, particularly [[science fiction]] helped to drive their friendship. Siegel has noted the [[John Carter (character)|John Carter]] stories as an influence: "Carter was able to leap great distances because the planet Mars was smaller that the planet Earth; and he had great strength. I visualized the planet Krypton as a huge planet, much larger than Earth".<ref name="AND8">Andrae (1983) [http://web.archive.org/web/20030924212234/superman.ws/seventy/interview/?part=8 p.8].</ref> The pair were also avid collectors of comic strips in their youth, cutting them from the newspaper, with [[Winsor McKay]]'s ''[[Little Nemo]]'' firing their imagination with its sense of fantasy.<ref>Andrae (1983), [http://web.archive.org/web/20031207221050/superman.ws/seventy/interview/?part=2 p.2].</ref> Shuster has remarked on the artists which played an important part in the development of his own style, whilst also noting a larger influence: "[[Alex Raymond]] and [[Burne Hogarth]] were my idols—also [[Milt Caniff]], [[Hal Foster]], and [[Roy Crane]]. But the movies were the greatest influence on our imagination: especially the films of [[Douglas Fairbanks]] Senior."<ref name="AND4">Andrae (1983), [http://web.archive.org/web/20031208131136/superman.ws/seventy/interview/?part=4 p.4].</ref> Fairbanks' role as [[Robin Hood (1922 film)|Robin Hood]] was certainly an inspiration, as Shuster admitted to basing Superman's stance upon scenes from the movie.<ref>Andrae (1983), [http://web.archive.org/web/20031208132241/superman.ws/seventy/interview/?part=7 p.7].</ref> The [[film|movies]] also influenced the storytelling and page layouts,<ref>Andrae (1983), [http://web.archive.org/web/20031208131627/superman.ws/seventy/interview/?part=5 p.5].</ref> whilst the city of Metropolis was named in honor of the [[Fritz Lang]] [[Metropolis (film)|movie of the same title]].<ref name="AND8"/>

===Copyright issues===
As part of the deal which saw Superman [[published]] in ''Action Comics'', Siegel and Shuster sold the [[Exclusive right|rights]] to the company in return for $130 and a contract to supply the publisher with material.<ref>{{cite news | first=Sam | last=Hurwitt | page=PK-24 | title= Comic Book Artist Populates Movies | date= [[January 16]], [[2005]] | publisher=[[San Francisco Chronicle]] | url= http://www.sfgate.com/cgi-bin/article.cgi?f=/chronicle/a/2005/01/16/PKGT6AJH9A1.DTL&type=movies |accessdate = 2006-12-08}}</ref><ref name="Heidi">MacDonald, Heidi.

The pair also sued [[DC Comics|Detective]] in the same year over the rights to [[Superboy]], which they claimed was a separate creation that [[DC Comics|Detective]] had published without authorization. [[DC Comics|Detective]] immediately fired them and took their byline off the stories, prompting a legal battle that ended in 1948, when a [[New York]] [[Supreme Court]] ruled that the 1938 contract should be upheld. However, a ruling from Justice J. Addison Young awarded them the rights to Superboy. A month after the Superboy judgement the two sides agreed on a [[settlement]]. [[DC Comics|Detective]] paid Siegel and Shuster $94,000 for the rights to [[Superboy]]. The pair also acknowledged in writing the company's ownership of Superman, attesting that they held rights for "all other forms of reproduction and presentation, whether now in existence or that may hereafter be created",<ref name="TCJ26313">Dean (2004), p. 13.</ref> but DC refused to re-hire them.<ref name="TCS73">Daniels (1998), p. 73.</ref>

In 1973 Siegel and Shuster again launched a [[suit]] claiming ownership of Superman, this time basing the claim on the [[Copyright Act of 1909]] which saw copyright granted for 28 years but allowed for a renewal of an extra 28 years. Their argument was that they had granted DC the copyright for only 28 years. The pair again lost this battle, both in a [[district court]] ruling of [[October 18]], [[1973]] and an [[appeal court]] ruling of [[December 5]] [[1974]].<ref name="TCJ2631415">Dean (2004), pp. 14-15.</ref>

In 1975 after news reports of their pauper-like existences, [[Warner Communications]] gave Siegel and Shuster lifetime [[pensions]] of $20,000 per year and [[Health care in the United States|health care benefits]]. Jay Emmett, then [[Vice president|executive vice president]] of Warner, was quoted in the ''[[New York Times]]'' as stating "There is no legal obligation, but I sure feel there is a moral obligation on our part."<ref name="TCJ26316">Dean (2004), p. 16.</ref> In addition, any media production which includes the Superman character were to include the credit "Superman created by Jerry Siegel and Joe Shuster".<ref name="Heidi"/>

[[Image:The Siegels.jpg|thumb|right|Jerry Siegel, with wife Joanne and daughter Laura in 1976. Joanne and Laura Siegel filed a termination notice on Jerry Siegel's share of the copyright of Superman in 1999.]]The year after this settlement, 1976, saw the copyright term extended again, this time for another 19 years to a total of 75 years. However, this time a clause was inserted into the extension to allow a creator to reclaim their work, reflecting the arguments Siegel and Shuster had made in 1973. The [[Copyright Act of 1976|new act]] came into power in 1978 and allowed a reclamation window in a period based on the previous copyright term of 56 years. This meant the copyright on Superman could be reclaimed between 1994 to 1999, based on the initial publication date of 1938. Jerry Siegel having died in January 1996, his wife and daughter filed a copyright termination notice in 1999. Although Joe Shuster died in July 1992, no termination was filed at this time by his [[Estate (law)|estate]].<ref name="TCJ26317">Dean (2004), p. 17.</ref>

1998 saw copyright extended again, with the [[Sonny Bono Copyright Term Extension Act]]. This time the copyright term was extended to 95 years, with a further window for reclamation introduced. In January of 2004 Mark Peary, nephew and legal [[heir]] to Joe Shuster's estate, filed notice of his intent to reclaim Shuster's half of the copyright, the termination effective in 2013.<ref name="TCJ26317"/> The status of Siegel's share of the copyright is now the subject of a legal battle. Warner Bros. and the Siegels entered into discussions on how to resolve the issues raised by the termination notice, but these discussions were set aside by the Siegels and in October 2004 they filed suit alleging copyright infringement on the part of Warner Bros. Warner Bros. counter sued, alleging the termination notice contains defects amongst other arguments.<ref name="TWOS">{{cite web| url =http://www.insidecounsel.com/issues/insidecounsel/15_159/profiles/191-1.html | title =The Woman Of Steel | accessdate =2007-01-26 | last =Vosper | first =Robert| year =2005 | month =February | publisher =[[Inside Counsel]] | quote =DC isn't going to hand over its most valued asset without putting up one hell of a legal battle }}</ref><ref>{{cite web| url =http://www.newsarama.com/DC/Superman/Intro.htm | title =Inside The Siegel/DC Battle For Superman | accessdate =2007-01-26 | last =Brady | first =Matt | date = [[March 3]], [[2005]] | publisher =[[Newsarama]] | quote = While the complaint, response and counterclaim has been filed, no one even remotely expects a slam-dunk win for either side.

{{main|History of Superman}}
{{see also|Kal-L}}

Superman, given the serial nature of comic publishing and the length of the character's existence, has evolved as a character as his adventures have increased.<ref name="TIME14388">{{cite news | first= Otto | last=Friedrich | page =9 | title=Up, Up and Awaaay!!! | date=Monday, [[March 14]], [[1988]] | publisher=''[[Time Magazine]]'' | url=http://www.time.com/time/magazine/article/0,9171,966978-9,00.html | accessdate =2007-01-28 }}</ref> The details of Superman's origin, relationships and abilities changed significantly during the course of the character's publication, from what is considered the [[Golden Age of comic books]] through the [[Modern Age of comic books|Modern Age]]. The powers and villains were developed through the 1940s, with Superman developing the ability to fly, and costumed villains introduced from 1941.<ref name="TCS67">Daniels (1998), p. 67.</ref> The character was shown as learning of the existence of [[Krypton]] in 1949. The concept itself had originally been established to the reader in 1939, in the [[Superman (comic strip)|Superman comic strip]].<ref name="TCS42">Daniels (1998), p. 42.</ref>

The 1960s saw the introduction of a second Superman, [[Kal-L]]. [[DC Comics|DC]] had established a [[Multiverse (DC Comics)|multiverse]] within the fictional universe its characters shared. This allowed characters published in the 1940s to exist alongside updated counterparts published in the 1960s. This was explained to the reader through the notion that the two groups of characters inhabited [[parallel Earths]]. The [[Kal-L|second Superman]] was introduced to explain to the reader Superman's membership of both the 1940s superhero team the [[Justice Society of America]] and the 1960s superhero team the [[Justice League of America]].<ref>{{Comic book reference | Writer = [[Denny O'Neil|O'Neil, Denny]] | Penciller = [[Dick Dillin|Dillin, Dick]] | Inker = [[Sid Greene|Greene, Sid]] | Story = Star Light, Star Bright--Death Star I See Tonight! | Title = Justice League of America | Volume = 1 | Issue = 73 | Date = August, 1969 | Publisher = [[DC Comics]] }}</ref>
[[Image:Deathofsuperman.jpg|thumb|200px|Art from ''Superman'' #75 (January 1993), where Superman dies in [[Lois Lane]]'s arms. Pencils by [[Dan Jurgens]].]]
The 1980s saw radical revisions of the character. DC Comics decided to remove the multiverse in a bid to simplify its comics line. This led to the rewriting of the [[back story]] of the characters DC published, Superman included. [[John Byrne]] rewrote Superman, removing many established conventions and characters from continuity, including [[Superboy]] and [[Supergirl]]. Byrne also re-established Superman's adoptive parents, [[Ma and Pa Kent|The Kents]], as characters.<ref>[[John Byrne|Byrne, John]] (w)(p), [[Dick Giordano|Giordano, Dick]] (i).

===Personality===
In the original Siegel and Shuster stories, Superman's personality is rough and aggressive. The character was seen stepping in to stop [[domestic violence|wife beaters]], profiteers, a [[lynch mob]] and gangsters, with rather rough edges and a looser moral code than audiences may be used to today.<ref name="60Y2223"/> Later writers have softened the character, and instilled a sense of idealism and moral code of conduct. Although not as cold-blooded as the early [[Batman]], the Superman featured in the comics of the 1930s is unconcerned about the harm his strength may cause, tossing villainous characters in such a manner that fatalities would presumably occur, although these were seldom shown explicitly on the page. This came to an end late in 1940, when new editor [[Whitney Ellsworth]] instituted a code of conduct for his characters to follow, banning Superman from ever killing.<ref name="TCS42"/>

In ''[[Superman/Batman]]'' #3, [[Batman]] thinks, "It is a remarkable dichotomy. In many ways, Clark is the most human of us all. Then...he shoots fire from the skies, and it is difficult not to think of him as a god. And how fortunate we all are that it does not occur to '''him'''."<ref>{{Comic book reference | Writer = [[Jeph Loeb|Loeb, Jeph]] | Penciller = [[Ed McGuinness|McGuinness, Ed]] | Inker = [[Dexter Vines|Vines, Dexter]] | Title = [[Superman/Batman]] | Volume =1 | Story = Running Wild | Issue = 3 | Date = December 2003 | Publisher = [[DC Comics]] }}</ref>

==Powers and abilities==
{{main|Powers and abilities of Superman}}
As an influential archetype of the superhero genre, Superman possesses extraordinary powers, with the character traditionally described as "faster than a speeding bullet, more powerful than a locomotive, and able to leap tall buildings in a single bound", a phrase coined by [[Jay Morton]] and first used in the ''Superman'' radio serials and [[Max Fleischer]] animated shorts of the 1940s<ref>{{cite news | title= Obituaries of note | date= [[September 25]], [[2003]] | work= [[St. Petersburg Times]] | url= http://www.sptimes.com/2003/09/25/Worldandnation/Obituaries_of_note.shtml | publisher=[[Wire services]] | accessdate = 2006-12-08}}</ref> as well as the TV series of the 1950s. For most of his existence, Superman's famous arsenal of powers include [[flight]], [[super-strength]], invulnerability to non-magical attacks of ordinary force, super-speed, vision powers (including [[x-ray vision|x-ray]], [[heat vision|heat]], telescopic, infra-red, and microscopic vision), super-hearing, and super-breath, which enables him to freeze objects by blowing on them, as well as exert the propulsive force of high-speed winds.<ref name="60Y80">Daniels (1995), p. 80.</ref>

As originally conceived and presented in his early stories, Superman's powers were relatively limited, consisting of superhuman strength that allowed him to lift a car over his head, run at amazing speeds and leap one-eighth of a mile, as well as incredibly tough skin that could be pierced by nothing less than an exploding artillery shell.<ref name="60Y80"/> Siegel and Shuster compared his strength and leaping abilities to an [[ant]] and a [[grasshopper]].<ref>{{Comic book reference | Writer = [[Jerry Siegel|Siegel, Jerry]] | Artist =[[Joe Shuster|Shuster, Joe]] | Story = A Scientific Explanation of Superman's Amazing Strength--! | Title = Superman | Volume = 1 | Issue = 1 | Date = Summer 1939 | Publisher = [[National Periodical Publications]] }}</ref> When making the cartoons, the [[Fleischer Brothers]] found it difficult to keep animating him leaping and requested to DC to change his ability to flying.<ref>[[Leslie Cabarga|Cabarga, Leslie]], [[Jerry Beck|Beck Jerry]], [[Richard Fleischer|Fleischer, Richard]] (Interviewees). (2006). "First Flight: The Fleischer Superman Series" (supplementary DVD documentary). ''[[Superman II]]'' (Two-Disc Special Edition) [DVD]. [[Warner Bros.]].</ref> Writers gradually increased his powers to larger extents during the [[Silver Age of comics|Silver Age]], in which Superman could fly to other worlds and galaxies and even across universes with relative ease.<ref name="60Y80"/> He would often fly across the solar system to stop meteors from hitting the Earth, or sometimes just to clear his head. Writers found it increasingly difficult to write Superman stories in which the character was believably challenged,<ref name="TCS133">Daniels (1998), p. 133.</ref> so [[DC Comics]] made a series of attempts to rein the character in. The most significant attempt, [[John Byrne]]'s 1986 rewrite, established several hard limits on his abilities: He barely survives a nuclear blast, and his space flights are limited by how long he can hold his breath.<ref name="AH96">{{cite journal | last =Sanderson | first =Peter | year =1986 | month =June | title = The End of History | journal =Amazing Heroes | issue =96 | id ={{ISSN|0745-6506}} }}</ref> Superman's power levels have again increased since then, with Superman currently possessing enough strength to hurl a mountain, withstand nuclear blasts with ease, and survive in the vacuum of outer space without oxygen.

The source of Superman's powers has changed subtly over the course of his history. It was originally stated that Superman's abilities derived from his Kryptonian heritage, which made him eons more evolved than [[humans]].<ref name="TCS42"/> This was soon amended, with the source for the powers now based upon the establishment of [[Krypton (planet)|Krypton]]'s [[gravity]] as having been stronger than that of the [[Earth]]. This situation mirrors that of [[Edgar Rice Burroughs]]' [[John Carter of Mars|John Carter]]. As Superman's powers increased, the implication that all Kryptonians had possessed the same abilities became problematic for writers, making it doubtful that a race of such beings could have been wiped out by something as trifling as an exploding planet. In part to counter this, the Superman writers established that Kryptonians, whose native star [[Rao (comics)|Rao]] had been red, only possessed superpowers under the light of a yellow [[sun]].<ref>{{cite web | url =http://www.msnbc.msn.com/id/13556951/ | title =Sex and the Superman | accessdate =2007-01-26 | last =Lundegaard | first =Erik | date = [[July 3]], [[2006]] | publisher =[[MSNBC]] | quote =Even his origin kept changing. Initially Krypton was populated by a race of supermen whose physical structure was millions of years more advanced than our own. Eventually the red sun/yellow sun dynamic was introduced, where Superman's level of power is dependent upon the amount of yellow solar radiation his cells have absorbed. }}</ref> More recent stories have attempted to find a balance between the two explanations.

Superman is most vulnerable to [[Kryptonite]], mineral debris from [[Krypton (planet)|Krypton]] transformed into radioactive material by the forces that destroyed the planet. Exposure to [[Kryptonite]] radiation nullifies Superman's powers and immobilizes him with pain; prolonged exposure will eventually kill him. The only mineral on Earth that can protect him from Kryptonite is lead, which blocks the radiation. Lead is also the only known substance that Superman cannot see through with his x-ray vision. Kryptonite was first introduced to the public in 1943 as a [[plot device]] to allow the radio serial [[voice actor]], [[Bud Collyer]], to take some time off.<ref name="TIME14388"/> Green Kryptonite is the most commonly seen form but writers introduced other forms over the years, such as red, gold, blue and black, each with its own effect.<ref name="TCS106107">Daniels (1998), pp. 106-107.</ref>

==Supporting cast==
{{main|Superman character and cast}}

[[Clark Kent]], Superman's [[secret identity]], was based partly on [[Harold Lloyd]] and named after [[Clark Gable]] and [[Kent Taylor]].<ref>{{cite news | first=John | last=Gross | title=Books of the Times | date=[[December 15]], [[1987]] | publisher=[[New York Times]] | url=http://query.nytimes.com/gst/fullpage.html?res=9B0DE3DC1F38F936A25751C1A961948260 |accessdate=2007-01-29 }}</ref> Creators have discussed the idea of whether Superman pretends to be Clark Kent or [[vice versa]], and at differing times in the publication either approach has been adopted.<ref>{{cite web| url =http://www.newsarama.com/TwoMorrows/BackIssue/20/BackIssue20.html | title = From Back Issue 20: Pro 2 Pro: A Clark Kent Roundtable | accessdate =2007-01-31 | last =Zeno | first =Eddy | authorlink =Eddy Zeno | date =[[December 25]], [[2006]] | format =excerpted from {{cite journal | year =2007 | month =January | title =The Clark Kent Roundtable | journal =Back Issue | issue =20 }} | work =newsarama.com | publisher =published on web by [[newsarama]], in print by [[TwoMorrow]] }}</ref><ref name="TKC119">Eury (2006), p. 119.</ref> Although typically a [[journalist|newspaper reporter]], during the 1970s the character left the ''[[Daily Planet]]'' for a time to work for television,<ref name="TKC119"/> whilst the 1980s revamp by [[John Byrne]] saw the character become somewhat more aggressive.<ref name="AH96"/> This aggressiveness has since faded with subsequent creators restoring the mild mannerisms traditional to the character.

Superman's large cast of supporting characters includes [[Lois Lane]], perhaps the character most commonly associated with Superman, being portrayed at different times as his colleague, competitor, love interest and/or wife. Other main supporting characters include ''[[Daily Planet]]'' coworkers such as photographer [[Jimmy Olsen]] and editor [[Perry White]], [[Clark Kent]]'s adopted parents [[Ma and Pa Kent|Jonathan]] and [[Martha Kent]], childhood sweetheart [[Lana Lang]] and best friend [[Pete Ross]], and former college love interest [[Lori Lemaris]] (a [[mermaid]]). Stories making reference to the possibility of Superman siring children have been featured both in and out of mainstream continuity.

Incarnations of [[Supergirl]], [[Krypto|Krypto the Superdog]], and [[Superboy]] have also been major characters in the mythos, as well as the [[Justice League|Justice League of America]] (of which Superman is usually a member). A feature shared by several supporting characters is [[alliteration|alliterative]] names, especially with the initials "LL", including [[Lex Luthor]], [[Lois Lane]], [[Supergirl (Kara Zor-El)|Linda Lee]], [[Lana Lang]], [[Lori Lemaris]] and [[Lucy Lane]],<ref>{{ Comic book reference | story=Superman's LL's [Text page] | title=[[Superman (comic book)|Superman]] | issue=204 | date=[[February]], [[1968]] | | publisher=[[DC Comics]] }}</ref> alliteration being common in early comics.

Team-ups with fellow comics icon [[Batman]] are common, inspiring many stories over the years. When paired, they are often referred to as the "World's Finest" in a nod to the name of the comic book series that features many team-up stories. In 2003, DC Comics began to publish a new series featuring the two characters titled ''[[Superman/Batman]]''.

Superman also has a [[rogues gallery]] of enemies, including his most well-known nemesis, [[Lex Luthor]], who has been envisioned over the years in various forms as either a [[mad scientist|rogue scientific genius]] with a personal vendetta against Superman, or a powerful but corrupt [[CEO]] of a conglomerate called [[LexCorp]].<ref name="TCS160">Daniels (1998), p. 160.</ref> In the 2000s, he even becomes [[President of the United States]],<ref>[[J.M. DeMatteis|, DeMatteis, J.M.]], [[Joe Kelly|Kelly, Joe]], [[Jeph Loeb|Loeb, Jeph]] ''et al'' (w), [[Ed McGuinness|McGuinness, Ed]], [[Duncan Rouleau|Rouleau, Duncan]], [[Paco Medina|Medina, Paco]] (a). ''Superman: President Lex'', NY:[[DC Comics]], [[July 1]] [[2003]]. ISBN 1563899744, ISBN 978-1563899744</ref> and has been depicted at various stages, as well as currently, as a former childhood friend of Clark Kent.

The alien [[android]] (in most incarnations) known as [[Brainiac (comics)|Brainiac]] is considered by Richard George to be the second most effective enemy of Superman.<ref>{{cite web | author = George, Richard | title = Superman's Dirty Dozen | publisher = IGN |page=2 | date = [[2006-06-22]] | url = http://uk.comics.ign.com/articles/713/713953p2.html | accessdate = 2007-01-11}}</ref> The enemy that accomplished the most, by actually killing Superman, is the raging monster [[Doomsday (comics)|Doomsday]]. [[Darkseid]], one of the most powerful beings in the [[DC Universe]], is also a formidable nemesis in most post-crisis comics. Other enemies who have featured in various incarnations of the character, from comic books to film and television include the fifth-dimensional [[imp]] [[Mr. Mxyzptlk]], the reverse Superman known as [[Bizarro]] and the Kryptonian criminal [[General Zod]].

==Cultural impact==

Superman has come to be seen as both an American cultural icon<ref>{{cite book | last=Magnussen | first=Anne | coauthors=Hans-Christian

===Merchandising===

Superman became popular very quickly, with an additional title, ''Superman Quarterly'' quickly added. In 1940 the character was represented in the annual [[Macy's parade]] for the first time.<ref>Staff writer. "Superman Struts In Macy Parade". ''[[New York Times]]'', [[November 22]], [[1940]]. p.18</ref> In fact Superman had become popular to the extent that in 1942, with sales of the character's three titles standing at a combined total of over 1.5 million, ''[[Time (magazine)|Time]]'' was reporting that "the Navy Department (had) ruled that Superman comic books should be included among essential supplies destined for the Marine garrison at Midway Islands."<ref>{{cite news | author=Staff writer | title=Superman's Dilemma | date=[[April 13]], [[1942]] |accessdate= 2007-01-29| publisher=[[Time (magazine)|Time]] | url=http://www.time.com/time/magazine/article/0,9171,766523,00.html }}</ref> The character was soon [[licensed]] by companies keen to cash in on this success through [[merchandising]]. The earliest paraphernalia appeared in 1939, a [[Campaign button|button]] proclaiming membership in the Supermen of America club. By 1940 the amount of merchandise available increased dramatically, with [[jigsaw puzzles]], [[doll|paper dolls]], [[bubble gum]] and [[trading cards]] available, as well as wooden or metal [[action figure|figures]]. The popularity of such merchandise increased when Superman was licensed to appear in other media, and Les Daniels has written that this represents "the start of the process that media moguls of later decades would describe as '[[synergy]].'"<ref name="TCS50">Daniels (1998), p. 50.</ref> By the release of ''[[Superman Returns]]'', [[Warner Bros.]] had arranged a cross promotion with [[Burger King]],<ref>{{cite web| url =http://www.mtv.com/movies/news/articles/1534100/20060612/story.jhtml | title =The 'Superman' Fanboy Dilemma, Part 4: Come On Feel The Toyz | accessdate =2007-01-16 | author =Karl Heitmueller | date =June 13 2006 | format =Flash | publisher =MTV News | quote =Warner Bros. has "Superman Returns" licensing deals with Mattel, Pepsi, Burger King, Duracell, Samsung, EA Games and Quaker State Motor Oil, to name a few. }}</ref> and licensed many other products for sale.

===Adaptations in other media===
{{main|Superman in popular culture}}
[[Image:Supermanflag.JPG|200px|left|thumb|[[Christopher Reeve]] as Superman in ''[[Superman II]]'']]The character of Superman has appeared in various media aside from comic books. This is in some part seen to be owing to the character's cited standing as an American cultural icon,<ref>{{cite journal | last =Jones | first =Cary M. | authorlink =Cary M.

The first adaptation of Superman was as a daily newspaper [[comic strip]], launching on January 16, 1939. The strip ran until May 1966, and significantly, Siegel and Shuster used the first strips to establish Superman's backstory, adding details such as the planet Krypton and Superman's father, [[Jor-El]], concepts not yet established in the comic books.<ref name="TCS42"/> Following on from the success of this was the first [[radio]] series, ''[[The Adventures of Superman (radio)|The Adventures of Superman]]'', which premiered on February 12, 1940 and featured the voice of [[Bud Collyer]] as Superman. The series ran until March, 1951. Collyer was also cast as the voice of Superman in the [[Fleischer Studios]] [[Superman (1940s cartoons)|animated cartoons]], distributed via movie theatres. Seventeen shorts were produced between 1941 and 1943. By 1948 Superman was back in the movie theatres, this time in a filmed [[serial]], ''[[Superman (serial)|Superman]]'', with [[Kirk Alyn]] becoming the first actor to portray Superman on screen. A second serial, ''[[Atom Man vs. Superman]]'', followed in 1950.<ref name="TCS7576">Daniels (1998), pp. 75-76.</ref>

In 1951 a television series was commissioned, starring [[George Reeves]], with the pilot episode of the series gaining a theatrical release as ''[[Superman and the Mole Men]]''. The series ran for a 104 episodes, from 1952 - 1958. The next adaptation of Superman occurred in 1966, when Superman was adapted for the stage in the [[Broadway theatre|Broadway]] [[musical theatre|musical]] ''[[It's a Bird...It's a Plane...It's Superman]]''. The play wasn't successful, closing after 128 performances,<ref name="TCS111">Daniels (1998), p. 111.</ref> although a [[cast album]] recording was released.<ref>{{cite web| url =http://www.amazon.com/Bird-Plane-Superman-Original-Broadway/dp/B0000027WB | title =Amazon.com: It's A Bird ... It's A Plane ...

Superman was again animated, this time for television, in the series "[[The New Adventures of Superman (TV series)|The New Adventures of Superman]]". 68 shorts were made and broadcast between 1966 and 1969. Bud Collyer again provided the voice for Superman. Then from 1973 until 1984 [[American Broadcasting Company|ABC]] broadcast the "[[Super Friends]]" series, this time animated by [[Hanna-Barbera]].<ref name="TCS111115">Daniels (1998), pp. 111-115</ref>

Superman returned to movie theatres in 1978, with director Richard Donner's ''[[Superman (1978 film)|Superman]]'' starring [[Christopher Reeve]]. The film spawned three sequels, ''[[Superman II]]'' (1980), ''[[Superman III]]'' (1983) and ''[[Superman IV: The Quest For Peace]]'' (1987).<ref name="TCS141143">Daniels (1998), pp. 141-143</ref> In 1988 Superman returned to television in the [[Ruby Spears]] animated series ''[[Superman (1988 TV series)|Superman]]'',<ref>{{cite web| url =http://www.rubyspears.com/film.shtml#C | title =About Us | accessdate =2007-01-11 |work=Ruby-Spears website |publisher=Ruby-Spears Productions | quote = Ruby-Spears pulled the coup of the 1988-89 season by acquiring the rights to two heavily sought after properties.

===Musical references, parodies and homages===
{{See also|Superman in popular music}}
Superman has also featured as an inspiration for musicians, with songs by numerous artists from several generations celebrating the character. [[Donovan]]'s [[Billboard Hot 100]] topping single "Sunshine Superman" utilised the character in both the title and the lyric, declaring "Superman and Green Lantern got nothing on me".<ref>[[Donovan]]. "[[Sunshine Superman (song)|Sunshine Superman]]." ''[[Sunshine Superman (1966 album)|Sunshine Superman]]''. [[Epic Records|Epic]], 1966.</ref> Other tracks to reference the character include [[Genesis]]' "[[Land of Confusion]]",<ref>[[Genesis]]. "[[Land of Confusion]]." ''[[Invisible Touch]]''. [[Atlantic Records]], 1986. "Ooh Superman where are you now, When everything's gone wrong somehow"</ref> the video to which featured a [[Spitting Image]] [[puppet]] of [[Ronald Reagan]] dressed as Superman,<ref>{{cite video | people =[[John Lloyd (writer)|Lloyd, John]] & Yukich, Jim (Directors) | year =1986 | title ="[[Land of Confusion]]" | medium =Music video | publisher =[[Atlantic Records]]}}</ref> and "Superman" by [[The Clique]], a track later covered by [[R.E.M.]] on their 1986 album ''[[Lifes Rich Pageant]]''. This cover is referenced by [[Grant Morrison]] in ''Animal Man'', in which Superman meets the character, and the track comes on [[Animal Man]]'s [[walkman]] immediately after.<ref>{{cite book |last=Morrison (w)|first=Grant |authorlink=Grant Morrison |coauthors=[[Chas Truog|Truog, Chas]], [[Doug Hazelwood|Hazlewood, Doug]] and [[Tom Grummett|Grummet, Tom]] (a) |editor=Michael Charles Hill (ed.)|others=[[John Costanza]] ([[letterer]]) & [[Tatjana Wood]] ([[colorist]]) |title=Animal Man |origyear=1991 |edition=1st edition |publisher=[[DC Comics]] |location=[[New York]] |isbn=1-56389-005-4 |page=45 |chapter=2: Life In The Concrete Jungle |quote=R.E.M. starts singing "Superman."

Parodies of Superman did not take long to appear, with ''[[Mighty Mouse]]'' introduced in "The Mouse of Tomorrow" animated short in 1942.<ref>{{cite news |first=Robin |last=Turner|title=Deputy Dawg |work=[[Western Mail]] |publisher=[[Western Mail and Echo Ltd]] |page=21 |date=[[August 8]], [[2006]]}}</ref> Whilst the character swiftly took on a life of its own, moving beyond parody, other animated characters soon took their turn to parody the character. In 1943 [[Bugs Bunny]] was featured in a short, ''[[Super-Rabbit]]'', which sees the character gaining powers through eating fortified carrots. This short ends with Bugs stepping into a phone booth to change into a real "Superman", and emerging as a [[U.S. Marine]].<ref>{{cite web| url =http://www.imdb.com/title/tt0036402/ | title =Super-Rabbit (1943) | accessdate =2007-01-16 | publisher =[[Internet Movie Database]] }}</ref> In 1956 [[Daffy Duck]] assumes the mantle of "Cluck Trent" in the short "Stupor Duck", a role later reprised in various issues of the ''Looney Tunes'' comic book.<ref>{{cite web| url =http://www.imdb.com/title/tt0049807/ | title =Stupor Duck (1956) | accessdate =2007-01-16 | publisher =[[Internet Movie Database]] }}</ref><ref>{{cite web| url =http://www.comics-db.com/comic-book/1046821-Looney_Tunes_97.html | title = Looney Tunes # 97 | accessdate =2007-01-16 | publisher =Big Comicbook Database}}</ref> In the [[United Kingdom]] [[Monty Python]] created the character Bicycle Repairman, who fixes bicycles on a world full of Supermen, for a sketch in series of their BBC show.<ref>{{cite news | first=Mel | last=Clarke | title=The Pitch | work =[[The Sunday Times (UK)|The Sunday Times]] |publisher=[[Times Newspapers Ltd]] | page=34 | date=[[August 1]], [[2004]] }}</ref> Also on the BBC was the [[sit-com]] "[[My Hero (TV series)|My Hero]]", which presented Thermoman as a slightly dense Superman pastiche, attempting to save the world and pursue romantic aspirations.<ref>{{cite news |first=Sally |last=Kinnes |title=The One To Watch |work=[[The Sunday Times (UK)|The Sunday Times]] |publisher=[[Times Newspapers Ltd]] |page=58 |date=[[January 30]], [[2000]] }}</ref> In America, ''[[Saturday Night Live]]'' has often parodied the figure, with [[Margot Kidder]] reprising her role as Lois Lane in a 1979 episode.<ref>{{cite web| url =http://www.imdb.com/title/tt0694925/ | title ="Saturday Night Live" Episode #4.15 (1979) | accessdate =2007-01-16 | publisher =[[Internet Movie Database]] }}</ref> [[Jerry Seinfeld]], a noted Superman fan, filled his series ''[[Seinfeld]]'' with references to the character, and in 1997 asked for Superman to co-star with him in a commercial for [[American Express]]. The commercial aired during the 1998 play offs and [[Super Bowl]], Superman animated in the style of artist [[Curt Swan]], again at the request of Seinfeld.<ref name="TCS185">Daniels (1998), p. 185.</ref>

Superman has also been used as reference point for writers, with [[Steven T. Seagle's]] graphic novel ''Superman: It's a Bird'' exploring Seagle's feelings on his own mortality as he struggles to develop a story for a Superman tale.<ref>{{cite web| url =http://www.ugo.com/channels/comics/features/itsabird/default.asp | title =Steven Seagle Talks ''It's a Bird'' | accessdate =2007-01-16 | publisher =ugo.com | quote =the semi-autobiographical tale of Steven being given the chance to write a Superman comic, but stumbling when he can't figure out how to relate to the character.

===Literary analysis===
Superman has been interpreted and discussed in many forms in the years since his debut. The character's status as the first costumed superhero has allowed him to be used in many studies discussing the genre, Umberto Eco noting that "he can be seen as the representative of all his similars".<ref>{{cite book |last=Eco |first=Umberto |authorlink=Umberto Eco |coauthors= |editor=Jeet Heer & Kent Worcester |title=Arguing Comics |origdate=1962 |year=2004 |publisher=University Press of Mississippi |isbn=1-57806-687-5|page=162 |chapter=The Myth of Superman }}</ref> Writing in ''[[Time Magazine]]'' in 1971, Gerald Clarke stated: "Superman's enormous popularity might be looked upon as signalling the beginning of the end for the Horatio Alger myth of the self-made man." Clarke viewed the comics characters as having to continuously update in order to maintain relevance, and thus representing the mood of the nation. He regarded Superman's character in the early seventies as a comment on the modern world, which he saw as a place in which "only the man with superpowers can survive and prosper."<ref>{{cite news |first=Gerald |last=Clarke |authorlink=Gerald Clarke|title=The Comics On The Couch |url=http://www.time.com/time/magazine/article/0,9171,842864,00.html | work=[[Time (magazine)|Time]] |publisher=[[Time Warner]] |id={{ISSN|0040-781X}} |pages=1-4 |date=[[December 13]], [[1971]] |accessdate=2007-01-29 }}</ref> Andrew Arnold, writing in the early 21st century, has noted Superman's partial role in exploring assimilation, the character's alien status allowing the reader to explore attempts to fit in on a somewhat superficial level.<ref>{{cite news |first=Andrew |last=Arnold |authorlink=Andrew Arnold |title=The Hard Knock Life |url=http://www.time.com/time/columnist/arnold/article/0,9565,1115061,00.html |work=[[Time (magazine)|Time]] |publisher=[[Time Warner]] |id={{ISSN|0040-781X}} |accessdate=2007-01-29 |quote=much of The Quitter involves the classic American literary theme of assimilation. Though extremely popular in other mediums, this theme, again, has gotten little attention in comix except obliquely, through such genre works as Seigel and Shuster's Superman character. }}</ref>

A.C. Grayling, writing in ''[[The Spectator]]'', traces Superman's stances through the decades, from his 1930s campaign against crime being relevant to a nation under the influence of [[Al Capone]], through the 1940s and [[World War II]], a period in which Superman helped sell war bonds,<ref name="60Y64">Daniels (1995), p. 64.</ref> and into the 1950s, where Superman explored the new technological threats. Grayling notes the period after the [[Cold War]] as being one where "matters become merely personal: the task of pitting his brawn against the brains of Lex Luthor and Brainiac appeared to be independent of bigger questions", and discusses events post [[9/11]], stating that as a nation "caught between the terrifying George W. Bush and the terrorist Osama bin Laden, America is in earnest need of a Saviour for everything from the minor inconveniences to the major horrors of world catastrophe. And here he is, the down-home clean-cut boy in the blue tights and red cape".<ref>{{cite news |first=A C |last=Grayling |title=The Philosophy of Superman: A Short Course |url=http://www.spectator.co.uk/archive/features/23525/the-philosophy-of-superman.thtml |format=Fee required |work=[[The Spectator]] |publisher=Press Holdings |id={{ISSN|0038-6952}} |date=[[July 8]], [[2006]] |accessdate=2007-01-29 }}</ref>[[Image:Clark-Kent.gif|thumb|right|Clark Kent, argued by [[Jules Feiffer]] to be the most innovative feature of Superman]]<!-- FAIR USE of Clark-Kent.gif: see image description page at http://en.wikipedia.org/wiki/Image:Clark-Kent.gif for rationale -->

[[Scott Bukatman]] has discussed Superman, and the superhero in general, noting the ways in which they humanize large urban areas through their use of the space, especially in Superman's ability to soar over the large skyscrapers of [[Metropolis]]. He writes that the character "represented, in 1938, a kind of Corbusierian ideal. Superman has X-ray vision: walls become permeable, transparent. Through his benign, controlled authority, Superman renders the city open, modernist and democratic; he furthers a sense that Le Corbusier described in 1925, namely, that 'Everything is known to us'."<ref name="MOG"/>

[[Jules Feiffer]] has argued that Superman's real innovation lay in the creation of the Clark Kent persona, noting that what "made Superman extraordinary was his point of origin: Clark Kent." Feiffer develops the theme to establish Superman's popularity in simple wish fulfilment,<ref>[[Jules Feiffer]] ''The Great Comic Book Heroes'', (2003). [[Fantagraphics]]. ISBN 1-56097-501-6</ref> a point Siegel and Shuster themselves supported, Siegel commenting that "If you're interested in what made Superman what it is, here's one of the keys to what made it universally acceptable. Joe and I had certain inhibitions... which led to wish-fulfillment which we expressed through our interest in science fiction and our comic strip. That's where the dual-identity concept came from" and Shuster supporting that as being "why so many people could relate to it".<ref>Andrae (1983), [http://web.archive.org/web/20031207220852/superman.ws/seventy/interview/?part=10 p.10].</ref>

Phospholipase Cleavage Sites. Note that an enzyme that displays both PLA1 and PLA2 activities is called a Phospholipase B

A phospholipase is an enzyme that converts phospholipids into fatty acids and other lipophilic substances. There are four major classes, termed A, B, C and D distinguished by what type of reaction they catalyze:

Types C and D are considered phosphodiesterases.
