Me TV is showing these on Saturdays, just before Batman and Wonder Woman. It's been years since I saw any, although I've seen most more than once. Except for the first one... and here I see one of the members of the Kryptonian ruling council (the obnoxious one with the black hair and moustache) wearing Captain Marvel's shirt...
My minion and I have been watching Batman ever since I found that the channel was showing it, when he was about 4 months old. I was excited when they added Wonder Woman, and now ecstatic that they've added Superman. Some of the minions first words were Spider-Man and Batman. One of these days I'll have to post some pictures of his "collection". It's coming close to surpassing my old Mego (and other) "collection".
I've been watching these sporadically, Batman is also being shown on the IFC Channel.
