Producer Sheldon Leonard took a big gamble with this series when it premiered on NBC back in October of 1965. Leonard,who at the time was producing shows like "Andy Griffith",and "Gomer Pyle", as well as "Dick Van Dyke at the time over at a rival network, was the first to present Bill Cosby (his series debut) as the first African-American to star in a prime-time series which was a milestone back then in a time of civil rights, and at the height of the Vietnam War. "I Spy" centered around two American agents who were sent in exotic places around the world as they face espionage adventures during their travels (which was also the first series to be filmed in very exotic places around the world like Japan, Mexico, Spain, and Greece). Kelly Robinson was the international tennis star (played by Robert Culp) who was a secret agent for the government along with his trainer Alexander Scott (played by Bill Cosby). These agents used their skill, and sometimes offbeat humor to crack cases or to spy on certain individuals.
The show was so quick and witty (and sometimes hilarious) with its cool and campy sort of humor, but it also had a dramatic side of it as well. The show ran on the NBC network from 1965-1968,and it was a great series giving Bill Cosby two Emmys for his work on the show.
