It's the same problem I have with sitcom reruns. All these companies bought up rights or consolidated what they had in the 90's, and they've pretty much refused to show them ON those cable stations now. WB keeps thinking Looney Tunes are a hard sell to kids,... well, they ARE if there's no where to put them. I saw both legit and copyright expired Looney Tunes compilations on television in syndication. Now, all they care about is trying to reboot a movie franchise of something that has NEVER been good at being long subject films. Even their best work was 90 minute theatrical clip shows.
Again, I know they put too much stock in LTBIA, but they also monkeyed the heck around with the film (I long to see a Donner Cut or the original script), taking the enjoyable stuff out. But then again, quality doesn't always equal box office performance (If so, Triplets of Belville should have broke records and Fast and Furious should never have seen 2, let alone 5), but it's like they didn't want to try very hard to compete with Elf (a movie I just can NOT watch the whole way through) and Cat in the Hat (not touching that one), which both trounced LT theatrically.
Of course, they gave us Baby Looney Tunes (which is cute for a line of baby products, don't get me wrong... but terrible for a TV show) and Loonatics Unleashed (another thing I'm not touching)... EVEN THOUGH Duck Dodgers, Taz-Mania, and Sylvester and Tweety Mysteries managed to keep them hip without reinveting the wheel... and LT classic cartoons were still on somewhere in some shape or form.
But I still don't see a compilation show, similar to all the ones they had up until the 00's on regular broadcast sometime either in the afternoon or weekends would hurt them so badly. Sigh.. I heard about the 60's and 70's... not only did they have compilation shows, but each channel had their OWN compilation show... some even ran AGAINST each other.
