Friendster
2002
The first social network to hit the big time and go mainstream, Friendster let members create profiles listing favorite movies and books (and dating status) and link up to friends, who linked to their friends, and so on. Friendster's dominance was brief, though. Ongoing technical snafus soon turned people off the site.
