For the first time in over 50 years and just in time for its 60th anniversary, Rudolph the Red-Nosed Reindeer is airing on its original broadcast home, NBC. Frosty the Snowman's also airing there. @tvmojoe.bsky.social has all the details here: https://www.vulture.com/article/rudolph-the-red-nosed-reindeer-nbc.html

CBS used to show Mickey's Christmas Carol too, but as with all Disney things, you're not seeing that over-the-air for free. anywhere.
That said, I doubt NBC's going to air Frosty Returns, and I don't think CBS will either. What's the point?
