No, they didn't. Facebook was just a less trashy, more exclusive version of myspace when it came out. Geocities, livejournal, blogger etc. were earlier iterations on the same concept - personal websites for non-techies. The only thing new about Facebook was their relative success in signing up a broader userbase, which was probably just a right-place, right-time thing of being around when computers and high-speed internet were becoming cheap and ubiquitous rather than anything different about what they were doing.
