Karim did not attend the party and denied that it had occurred, but Chen commented that the idea that You Tube was founded after a dinner party "was probably very strengthened by marketing ideas around creating a story that was very digestible".
Karim said the inspiration for You Tube first came from Janet Jackson's role in the 2004 Super Bowl incident, when her breast was exposed during her performance, and later from the 2004 Indian Ocean tsunami.
Videos deemed potentially inappropriate are available only to registered users affirming themselves to be at least 18 years old.
