From 1950 to 1966, the game show was broadcast in black and white, as was typical of most game shows at the time. But by 1966, all three networks were broadcasting their prime-time schedules entirely in color television, including "What's My Line?" After the show ended in 1967, CBS replaced the color videotapes with the kinescope versions instead for syndication. As a result of this change, the 1966–1967 episodes of "What's My Line?" were only shown in black-and-white after the show ended.
