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

[Telecolor 3007]

Wow. In just 2 years the number of color tv sets sold increased 3 times.
The number of color sets sold overcome the number of black and white set sold in 1972 as far as I know.
In Western Europe it took about 10-12 years for the number of color sets to outnumber the numer of b & w sets. But Europeanens got a little bit less costly production methodes and where closer to more modern tehcnologies (solid state sets, in line picture tubes). In Eastern-Europe the number of color sets increased only after 1989.
Yes, a lot of old set where expensive, but the people got jobs manufacturing/assembling them... now in a lot of countries those jobs are gone
As we get close to modern times, the time of adopting new techology is decreasing. But it's strange how modern technology is not uniting people... it's making them become lonlier. Oh, it's a pitty that isn't like in the old days when you invited people to you in order to see movies on V.H.S., L.D., D.V.D.

@ EricH : why it took so long for your family to get a color set?
In Romania... but that's another story.
