YouTube was initially launched as a video dating site, but it quickly shifted to a general-purpose video sharing platform. The site's founders offered $20 to women who uploaded self-introduction videos, but after 5 days, the site had no user-uploaded content. The first video ever uploaded to YouTube was a 19-second video titled 'Me at the zoo'. The site's evolution from a dating site to a video sharing platform is an interesting example of how a startup can pivot and find success in a different direction.
