Night Gallery.
I'm too young to have been around when it first premiered (1969, I was born 1988), but I have seen it on DVD when my cousin brought back the 1st season box set after a visit to the US, and I was amazed. It was well written, scary and always kept you on your feet, plus it was narrated by Rod Serling himself, who, if you've seen Twilight Zone, is THE penultimate horror anthology narrator, second maybe to Alfred Hitchcock only. It lasted 3 seasons and ended in 1973, but from what I can tell, was a good run all throughout.
