2 Inspired by Hotornot
Youtube started as a dating site that was inspired by Hotornot, the site that allowed people to rate the attractiveness of others before dating them. The idea was mainly a site that allowed people to upload videos of themselves for dating purposes.
3 Two events are believed to have inspired the idea of the YouTube we know today
It's believed that Karim, one of the founders, was unable to find an important video of Janet Jackson online. Hurley and Chen, the other founders, were also unable to share a video of a dinner party they attended without Karim through email.
