YouTube's mythic dinner party
YouTube's mythic dinner party

YouTube, according to popular legend, began at a 2005 dinner party at 27-year-old co-founder Steve Chen's San Francisco apartment. Chen and his friend Chad Hurley shot videos at the party, then had trouble finding a place to share them online, they said. Voila! A $1.7 billion business was born.

Only problem: The third YouTube co-founder, Jawed Karim, says the party never happened, and the idea of online video sharing was originally his. Chen insist the party was real, but admitted to Time magazine in 2006 that the tale "was probably very strengthened by marketing ideas around creating a story that was very digestible."
