CNN - Operation Match, launched in 1965 by Harvard students Jeff Tarr and Vaughan Morrill, was the first computer matchmaking service in the U.S. Using a 75-question survey, it connected thousands of date-seeking college students. Participants received potential matches' phone numbers for a $3 fee. However, the first computerized dating service was actually Joan Ball' UK-based St. James Computer Dating Service, which made its first match in 1964, a year before Operation Match went online.
