In 1994, Andrew Conru created the first online dating site, WebPersonals. After selling that site in 1995, he launched FriendFinder.com, an early social networking site, in 1996. Days after the site went live, Conru found that people were posting naked pictures of themselves and seeking partners for adult-oriented activities. As a result, Conru started Adult FriendFinder, which he described as "a release valve". FriendFinder has since established other niche dating sites, including Senior FriendFinder, Amigos.com, BigChurch.com, and Alt.com.
