Rules: Don't take too long to think about it. Fifteen tv series you've seen all/most of the episodes of that will always stick with you. Series you have bought/would buy on DVD, if money were no object. First fifteen you can recall in no more than fifteen minutes.
Captain Midnight (Ovaltine shill in the 50s, turned into a tv series after being a successful radio series in the 40s)
Twilight Zone (Rod Serling did some great stuff)
Star Trek TOS
Monty Python (I want a Norwegian Blue parrot!)
Kung Fu (In modern parlance this series jumped the shark from the first episode but it was sooooo entertaining)
