Genius is an online media knowledge base founded on October 2009 by Mahbod Moghadam, Tom Lehman, and Ilan Zechory. The site allows users to provide annotations and interpretation of song lyrics, news stories, sources, poetry, and documents. Originally launched as Rap Genius with a focus on hip hop music, the site expanded in 2014 to cover other forms of media, such as pop, literature, R&B, and added an annotation-embedded platform. That same year, an iPhone app was released. To reflect these new goals, the site re-launched as Genius in July 2014. An Android version was released in August 2015. Rap Genius was created in October 2009 by founders Mahbod Moghadam, Tom Lehman, and Ilan Zechory, who met during their undergraduate years at Yale University. Lehman and Moghadam came up with the idea for the site in the summer of 2009 when Lehman asked Moghadam about the meaning of a Cam'ron lyric. After Lehman built the earliest version of the site, Moghadam, a 2008 graduate of Stanford Law School and a first year employee at Dewey and LeBoeuf who was on a paid sabbatical leave, decided to pursue the idea full-time. Lehman, the programmer of the site, and Zechory soon joined him and brought the idea to fruition. Originally named Rap Exegesis, the site changed its name in December 2009 to Rap Genius because "exegesis" was difficult for users to spell. The ability to listen to the songs while viewing their lyrics, the Rap Map, and Music Video annotations were eventually added to the site as well.
