I got this one out of chronological order for some reason. I think I was looking at the last time Morgan Freeman played Dracula on The Electric Company instead of the first. As far as I can tell, he was playing Dracula in the first season, which started in ’71.
If you’re too young to remember The Electric Company, it was from the makers of Sesame Street and was designed to introduce older kids to reading fundamentals and foster a love for reading. My brothers and I never exactly “graduated” from Sesame Street to The Electric Company. We just enjoyed both for different reasons. Morgan Freeman is no Count von Count, but he has his own campy charm. He’ll always be the one, true Blacula to me.

Watch The Electric Company, a lot. Remember his Drac very well!
They way "Casket" appears on the screen before introducing the Count makes me think this could be a sitcom about a vampire named "Casket". He'd have wacky conversations with his roommate Renfeld. Wait, a minute "Renfeld" is only two letters different from "Seinfeld", yes this could totally work as a sitcom!
If Jason Alexander can play Renfeld, I'm in!
