In 1979 I was walking through University Mall in Pensacola, Florida and a TV store had movie posters of "Chinatown" in the window.
This was at a time when only Sony Betamax VCR's were available, and they were expensive and were primary used to record from television since there was little or no theatrical films yet available.
I asked the man what's with the "Chinatown" poster, he said we've got the new RCA video-disc player for $499.00, you can play movies at home on your television. I said do you have "Chinatown"? He said yes, it's $24.99, I said I'll take one video player and one "Chinatown" video-disc.
