What if Adult Swim had never happened?

Inspired by a thread that I read while lurking on Toon Zone, I thought that I would pose this purely hypothetical question: What would Cartoon Network be like today if the Adult Swim block had never entered the picture? What would CN be airing during the hours after 9PM? Would Boomerang still be just a program block airing during the wee hours instead of the sister channel/recycle bin for CN than it is now? Would shows like O, Canada, Toon Heads, Space Ghost: Coast to Coast, Cartoon Planet and Late Night Black and White still be around? Would CN's prime time lineup extend past 9PM? Would shows like The Boondocks, The Oblongs, Aqua Teen Hunger Force and Harvey Birdman: Attorney At Law have even aired on Toon at all without AS? Where would shows like Delocated, Children's Hospital or Eagleheart have gone if there had been no AS block? Would would CN's weekend schedule be like? The mind boggles.

Here's what I would do if I were running a Cartoon Network without Adult Swim: I would extinguish the Boomerang channel and have Boom go back to being a program block on Cartoon Network. CN prime-time would run from 8PM to 11PM Monday through Friday, and then Boomerang (again, the program block, not the channel) would run on weeknights from 11PM to 6AM. On weekends I would resurrect an evening premiere block (similar to the now defunct You Are Here or Toonmai, except with a unified brand name) which would air on weekends from 10PM to about 2AM (or possibly the block could premiere during the prime time hours and have encores during the late night hours). Friday nights would be for comedy premieres, Saturday nights would be for action premieres and Sunday nights would be adult night, airing such shows as the aforementioned Space Ghost: C2C, The Oblongs, Aqua Teen Hunger Force, Robot Chicken and the like. I'd like to give each night for this block a catchy name like The Hub's "Saturday Mash-Up" (with "Crack-Up", "Smash-Up", "Team-Up", etc.), but I haven't thought of a good name yet.

Anyways, I would call the after 11PM CN schedule by the handle CNPM, inspired by an idea of my brother's. The logo bug on the corner of the screen would be the current CN logo with an additional blue tile with the letters P and M printed in white in the same CN font.

Thoughts?
