The Bugs Bunny cartoons on Saturday Mornings in the 80's (and all Looney Tunes for that matter, up till the advent of The Sylvester & Tweety Mysteries in 1995) were simple re-bundlings of the enormous Warner Brothers Animation Archives. All though it wa 1980, the newest cartoon you would see on these shows was animated way back in the 1960's.

The Tom & Jerry Comedy Show, though... *shudder*.
