Jones and Seuss Rule

Here's an interesting data point.

... NBC’s rebroadcast of “How the Grinch Stole Christmas” at 8 p.m. was the top-rated telecast of the night on an evening of comprised entirely of reruns. The classic Dr. Seuss animated special drew a 1.2 rating in the advertiser-coveted 18-49 demo, according to Nielsen overnight numbers. ...

You won't find a lot of live-action programming from the middle sixties that gets aired, let alone pulls numbers.

But animated shows do it again ... and again ... and again. There's Charlie Brown. There's Rudolph and Frosty and (of course) the Grinch. This might explain why our fine entertainment conglomerates keep making animated product.
