Six Degrees is widely considered to be the very first social networking site. Founded by Andrew Weinreich in May 1996, the site launched the following year and combined popular features such as profiles, friends lists and school affiliations in one service. While the site had millions of registered users, due to the lack of people connected to the Internet, networks were limited. It would be a few years before the Internet's infrastructure could catch up with the concept of social networks. The site was sold in December 2000 to YouthStream Media Networks.
