One of the first, GUNSMOKE.
The television series ran for 20 seasons from 1955 to 1975, and lasted for 635 episodes.
Now 67 years later, it is still on several cable tv channels multiple times a day and everyday of the week.
What's really amazing, that in todays world of political correctness or whatever you want to call it, Every episode started with a shootout, and multiple shootings through out each show.
And yes I still watch it just about everyday 67 years later.
