The RKO Radio Picture logo is significant mainly because it told us we were about to see a picture with Fred Astaire and Ginger Rogers in it. It's too bad we don't have that compelling morse code beeping in the background. Someone finally deciphered what the morse code stood for. No, not something indescribably filthy! It just says "A Radio Picture".
Nice early Warner title, if a bit static. I wish they'd stuck with this one - I never liked that obnoxious WB logo thrusting at us, which went along with the equally-obnoxious "doyyyyy" of Bugs Bunny cartoons.
This is the best CBS eye "aperture" logo I've been able to find. Not the greatest, but the few others I've found are closely attached to end credits and can't be isolated. These gifs don't make themselves, you know, and some of them take a long time.
One of the strangest logos I've ever seen: a real find. This is why I keep chopping my way through bad copies of bad logos late at night, because once in a while I garner a gem like this one. I've always loved the Pathe rooster because he seems to take an iconoclastic stand against roaring lions and all that MGM spectacle crap. Give me a crowing cock any day.
