This channel was called "Showbiz" and we got it in rural San Diego county because cable did not reach us back then. Showbiz was available as a pay service but it was broadcast locally.
It reminds me of Z channel because it showed odd little films and felt like there was a "DJ" picking out films to show me that I would never have thought to see.
This channel's programing introduced me to Austrailian films, which in the late 70's and early 80's were very interesting.
If someone can respond with a URL or other data I would be most appreciative.
