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. Launched as Rap Genius with a focus on rap, the site expanded in 2014 to cover other forms of media, such as pop, literature and R&B, and 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.
