Vintage clip on YouTube about compatible colour television

[Aussie Bloke]

I found an interesting clip on YouTube http://www.youtube.com/watch?v=ojJCJIaDp9Q which is an announcement of compatible colour television by a NBC spokesman which aired during the Sid Caesar Hour in 1955. He announced that RCA has won the colour compatible television standards fight over CBS sequential field colour system and that the colour TVs are soon available for purchase. I personally would say this clip would date 1953 not 1955.
