There were several million TV sets in operation in the US by the end of 1949.

I think they only had one channel as well. Depends on where you lived. For example, New York City had six stations by the end of 1949 (WCBS-TV, WNBT, WABD, WATV, WPIX, and WJZ-TV), while Philadelphia had three stations by the end of 1949. Don't know if anyone cares, but apart from the U.S, other countries with TV in the late-1940s included the former USSR, France and Britain. |

Yep, what's also cool is the National Television System Committee established the black and white TV system all the way back in 1941. With color being added to the system in 1950. A single fluctuating voltage is all that is required to relay a full color picture. That system of TV is still around in some parts of the world, and was only turned of in the states recently. It made it just over 60 years without being changed. Analog TV is one of the major electrical engineering accomplishments of the 20th century IMO, I still find it technically amazing today. I'm not sure about the latest generation, but the previous gen of games consoles (PS3/XBOX-360/WII) can output analog NTSC (a 60 year old protocol). Joke for those who are interested in this kind of thing: NTSC = Never The Same Color.  |
