Black TV and white TV in 1970's?

Answer 1

By the 1970s color television was reaching twenty years old in the US and was making a big impact in the UK and Europe. Although some countries did not start a color television service until the late 70s, most had color firmly established in the early 1970s.

Black and white televisions remained on the market for many years and it is only in the 21st century that black and white models have finally disappeared from the shelves of electronics stores.
