Xkcd began in September 2005, when Munroe decided to scan his doodles and put them on his personal website. By the time he graduated from college, Munroe's 'piles of notebooks' became too large and he started scanning the images.

History Īs a student, Munroe often drew charts, maps, and 'stick figure battles' in the margins of his school notebooks, besides solving mathematical problems unrelated to his classes. A fifth book, What If? 2, was released on September 13, 2022.

A fourth book, How To, which is described as 'a profoundly unhelpful self-help book', was released on September 3, 2019. His 2015 book Thing Explainer explains scientific concepts using only the one thousand most commonly used words in English. The What If column on the site is updated with new articles from time to time. His 2014 book What If? is based on his blog of the same name that answers unusual science questions from readers in a light-hearted way that is scientifically grounded. The first book, published in 2010 and entitled xkcd: volume 0, was a series of select comics from his website. Munroe has released five spinoff books from the comic. New cartoons are added three times a week, on Mondays, Wednesdays, and Fridays. It has a cast of stick figures, and the comic occasionally features landscapes, graphs, charts, and intricate mathematical patterns such as fractals. Some strips feature simple humor or pop-culture references. The subject matter of the comic varies from statements on life and love to mathematical, programming, and scientific in-jokes. Munroe states on the comic's website that the name of the comic is not an initialism but 'just a word with no phonetic pronunciation'. The comic's tagline describes it as 'a webcomic of romance, sarcasm, math, and language'. Xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe.
