xkcd, sometimes stylized as XKCD, is a webcomic created by Randall Munroe. The comic's tagline describes it as "a webcomic of romance, sarcasm, math, and language."[‡ 1] Munroe mentions on the comic's website that the name of the comic is not an acronym but "just a word with no phonetic pronunciation".

The subject matter of the comic varies from statements on life and love to mathematical and scientific in-jokes. Some strips feature simple humor or pop-culture references. Although it has a cast of stick figures,[2][3] the comic occasionally features landscapes, intricate mathematical patterns such as fractals (for example, strip No. 17 "What If"[‡ 2] shows an Apollonian gasket), intricate graphs and charts, or imitations of the style of other cartoonists (as during "Parody Week").[4]

xkcd is available under the Creative Commons Attribution-NonCommercial 2.5 License.[‡ 3] New comics are added three times a week, on Mondays, Wednesdays, and Fridays,[‡ 1][5] although on some occasions they have been updated every weekday.

Since July 2012, there has been a branch of xkcd called xkcd What-If, updated every Tuesday. These attempt to answer unusual reader-submitted science questions in a humorous—though mathematically sound—way, in a format more like an article rather than a traditional comic strip.[6][7]

History[edit]

Randall Munroe, the creator of xkcd

The comic began in September 2005 when Munroe decided to scan doodles from his school notebooks and put them on his webpage. Eventually the comic was split off into its own website, where Munroe started selling T-shirts based on the comic. He currently "works on the comic full-time,"[‡ 1] making Munroe one of the few professional webcomic artists.[8]

According to Munroe, the comic's name has no particular significance and is simply a four-letter word without a phonetic pronunciation, something he describes as "a treasured and carefully guarded point in the space of four-character strings." The name of the comic is spelled in all lowercase letters, or all capitals.[‡ 1]

In May 2007, the comic garnered widespread attention by depicting online communities in geographic form.[9] Various websites were drawn as continents, each sized according to their relative popularity and located according to their general subject matter.[9] This put xkcd at number two on the Syracuse Post-Standard's "The new hotness" list.[10]

In October 2008, The New Yorker magazine online published an interview and "Cartoon Off" between Randall Munroe and Farley Katz. For the "Cartoon-Off", Katz and Munroe each drew: "the Internet, as envisioned by the elderly", "String Theory", "1999", and "your favorite animal eating your favorite food".[11]

In March 2010, a puzzle hidden inside of the collection xkcd: Volume 0 was cracked by many members of the xkcd forums. The solution was "<3<3<3 2010-06-26 14:28:57 37°46′10″N 122°28′59″W / 37.769573°N 122.483123°W / 37.769573; -122.483123"—ASCII art hearts, followed by the timestamp for June 26, 2010, 2:28:57 pm, and the coordinates Google Earth specifies for Golden Gate Park."[‡ 4] At the specified time, date, and location, Munroe met with fans and handed out 255 limited edition prints of xkcd: Volume 0, titled xkcd: Volume 0 Service Pack 1.[‡ 5]

For April Fools Day 2012, comic № 1037 ("Umwelt") displayed different comics depending on browser, location, and IP address range.[‡ 6][‡ 7]

On September 19, 2012, comic № 1110 ("Click and Drag"), featured a panel which can be explored via clicking and dragging its insides.[‡ 8] It immediately triggered positive response on social websites and forums.[12] The large image measures 165,888 pixels wide by 79,822 pixels high.[13]

Comic number 1190 ("Time") began publication at midnight EDT on March 25, 2013, with the comic's image updating every 30 minutes until March 30, when they began to change every hour, lasting for over four months. The images constitute time lapse frames of a story, with the mouseover text originally reading "Wait for it.", later changed "RUN." and changed again to "The end." on July 26. The story began with a male and female character building a sandcastle complex on a beach who then embark on an adventure to learn the secrets of the sea. On July 26, the comic superimposed a frame (3094) with the phrase "The End". Tasha Robinson of The A.V. Club wrote of the comic: "[...] the kind of nifty experiment that keeps people coming back to XKCD, which at its best isn't a strip comic so much as an idea factory and a shared experience".[14] Cory Doctorow mentioned "Time" in a brief article on Boing Boing on April 7, saying the comic was "coming along nicely". The 3,099-panel "Time" comic ended on July 26, 2013 and the "secret" backstory has now been revealed.[15]

For April Fools Day 2013, comic № 1193 ("Externalities") changed its text content over that day, depending on various external values, from the amount of money donated to the Wikimedia Foundation via a link in the comic, to the school of first- and third-place winners of an xkcd hash-finding competition at http://almamater.xkcd.com/.[16]

Recurring items[edit]

While there is no specific storyline to the comic, there are some recurring themes and characters,[17] many of which are touched on in an xkcd parody of the Discovery Channel's I Love the World advertising campaign,[‡ 9] which was later reenacted by Neil Gaiman, Wil Wheaton, and Cory Doctorow,[18] directed and recorded by musician Olga Nunes.

Themes[edit]

"Wikipedian Protester", with mouseover text "SEMI-PROTECT THE CONSTITUTION"

A large number of the strips contain mathematics or computer science jokes. These jokes often feature university-level subjects, although many are written in such a way that a clear understanding of the subject is not required to get the punch line.

Romance is another subject often visited in the comic, with many strips not intended to be humorous;[17] Munroe is a self-declared fan of artist Kurt Halsey's bleak romances. There are also many strips opening with "My Hobby:" and usually depicting the nondescript narrator character describing some type of humorous or quirky behavior often involving language games.[‡ 10][‡ 11][‡ 12][‡ 13]

"Malamanteau",[‡ 14] with mouseover text "The article has twenty-three citations, one of which is an obscure manuscript from the 1490s and the other twenty-two are arguments on Language Log."

References to Wikipedia articles or to Wikipedia as a whole have occurred several times in xkcd.[‡ 14][‡ 15][‡ 16][‡ 17][‡ 18][‡ 19][‡ 20] A facsimile of a made-up Wikipedia entry for "malamanteau" (a stunt word created by Munroe to poke fun at Wikipedia's writing style)[‡ 14] provoked a controversy within Wikipedia that was picked up by various media.[19][20]

xkcd frequently makes reference to Munroe's "obsession" with potential raptor attacks,[21] and has used many "your mom" jokes.[‡ 21][‡ 22][‡ 23][‡ 24] Multiple earlier strips featured "Red Spiders",[‡ 25][‡ 26][‡ 27][‡ 28] and others refer to Joss Whedon's science fiction series Firefly.[‡ 29] Munroe at one point drew several strips addressing his fiancee's ongoing treatment for breast cancer.[‡ 30]

Each comic has a tooltip (specified using the title attribute in HTML). The text usually contains a secondary punchline or annotation related to that day's comic.[22]

Characters[edit]

Although Munroe does not maintain a list of characters on his web site, some recurring characters can be identified by their visual features (for example, hats) and mannerisms.

In the "Secretary" story arc, Black Hat is nominated for the post of Secretary of the Internet when the Internet starts to collapse. After a variety of hijinks involving Ron Paul, Cory Doctorow, and the Auto-Troll Shuffle (described by him as taking a whole car apart, swapping the parts with the same parts of random cars in the same parking lot, and then building a new car out of them), he is sentenced to death. He escapes by filling the Capitol rotunda with plastic ball pit-style balls, distracting his pursuers while he flees on Doctorow's hot-air balloon.[‡ 37] Since comic 433 "Journal 5" he has been in a relationship with "psychotic female". His apartment is outfitted with a moat.[‡ 38]
A similar character appeared earlier in comic 177, "Alice and Bob", where she is referred to as "Eve".[‡ 46]

Inspired activities[edit]

On several occasions, fans have been motivated by Munroe's comics to carry out, in real life, the subject of a particular drawing or sketch. Some examples include:

Awards and recognition[edit]

xkcd has been recognized at the Web Cartoonists' Choice Awards. In the 2008 Awards, it was nominated for "Outstanding Use of the Medium", "Outstanding Short Form Comic", and "Outstanding Comedic Comic", and won "Outstanding Single Panel Comic".[45] xkcd was also voted Best Comic Strip by readers in the 2007 Weblog Awards[46] and 2008 Weblog Awards.[47] It was also nominated for a 2009 NewNowNext Award in the category 'OMFG Internet Award'.[48][49] Randall Munroe was nominated for the Hugo Award for Best Fan Artist in both 2011 and 2012,[50][51] as well as for Best Graphic Story in 2014, for "Time".[52]

Translations[edit]

xkcd comics have been translated into a number of languages. One group of readers has translated every comic into French[‡ 81] and nearly half of the comics have been translated into Russian.[‡ 82] One reader has translated many of the comics into Spanish; translations exist for comics that, according to the translator, can be translated without losing their humor.[‡ 83] Various xkcd comics have also been translated into German,[‡ 84] Finnish,[‡ 85] Czech,[‡ 86] Portuguese,[‡ 87] Esperanto,[‡ 88] Lojban,[‡ 89] and Yiddish.[‡ 90]

Books[edit]

In September 2009, Munroe released a book, entitled xkcd: volume 0, containing selected xkcd comics.[‡ 91] The book was published by breadpig, under a Creative Commons license, CC BY-NC 3.0,[53] with all of the publisher's profits donated to Room to Read to promote literacy and education in the developing world. Six months after release, the book had sold over 25,000 copies. The book tour in New York City and Silicon Valley was a fundraiser for Room to Read that raised $32,000 to build a school in Salavan Province, Laos.[54][55]

In October 2012, xkcd: volume 0 was included in the Humble Bundle eBook Bundle. It was available for download only to those who donated higher than the average donated for the other eBooks. The book was released DRM-free, in two different-quality PDF files.[56]

On March 12, 2014, Randall Munroe announced the book ″What If?: Serious Scientific Answers to Absurd Hypothetical Questions″. The book's release date is September 2, 2014. The book expands on the What-If series on the website.[57][58]
