Well, the world came into color about late 61, early 62 and it took scientists to convert that to television late 63, so, yeah, 1964 would be about the time color came to television on a mass scale.
I’d have to disagree with you guys. I seem to remember that 1967 was the year that color became the standard on tv.
Some of the shows that went from B&W in 1966 to color in 1967:
The Monkees, The Beverly Hillbillies, Gilligan’s Island, etc...
