Rap Genius was originally called RapExegesis.com. Then they made a public post asking for better company name ideas- http://forumserver.twoplustwo.com/19/high-stakes-pl-nl/ot-he...

I always thought this was fascinating and makes me think of the implications of happenstance. A company called Genius whose first domain had the word rape in it, which was promoted by a poker player who once created his own personal TV commercial and ran it via Google TV ads- https://www.youtube.com/watch?v=ocekqhrmPNo

But give them $20 million and say they are pioneers in a general space that's decades old, and suddenly Genius is pioneering annotations and redefining fair use.
