CHICAGO TRIBUNE - Nov 22 - Online dating has a relatively short history characterized by explosive growth in recent years, experts say. Most consider Match.com, launched in 1995, to be the first Internet dating site. The company was a pioneer, but using computers to connect eligible singles predates Match.com by decades. In the mid-1960s two Harvard undergraduates came up with "Operation Match," a computer program that paired men and woman based on a series of questions. Online dating also has become big business. According to IBISWorld, ~3,700 dating service companies generate ~$2 billion in annual revenue.
