Premiered: September 15, 1965, on NBC
Premise: Seriocomic espionage about two American agents working undercover, traveling the globe as a tennis pro and his trainer. Previously known only as a stand-up comedian, Bill Cosby---the first black to star in a regular series, though race was never an issue on the show---proved to be a natural as an actor and won the Emmy three years in a row. `I'd like to thank NBC for having guts,' he said following his first win. In 1994, they reunited for a TV-movie, `I Spy Returns.'
