Why the color tv sets where so expensive at the beging?

[etype2]

All three major networks, NBC, CBS and ABC went 100% color in the 1966/67 prime time season. This together with dropping prices spurred a rush to color by the buying public.

There were many publications saying color television was finally ready for prime time and the public was eger to adopt. I was 19 at the time (1966) and purchased my first color television which was a RCA 19 inch rectangular console.
