I know this isn't retro because it lasted 2000-2004 but i'm just curious does anyone here happen to remember the Boomerang block that used to come on Cartoon Network on weekends? It used to come on weekend mornings from 6am-8am and I believe when CN first created the Boom channel to begin with they had a sunday evening and saturday afternoon Boom blocks too the sunday evening Boom block was pulled first than the saturday afternoon block was pulled next leaving the weekend morn block the exclusive Boom block on the network but than the saturday afternoon block made a very brief return but than not too long after the weekend morning block was the exclusive Boom block yet again than it was cut down to only saturdays from 6am-8am than it became weekends from 6am-7am than it was weekends at 6am than it was gone. This Boom block was run a bit differnt from the channel the channel you see actually had a schedule with shows with perm slots the block would just re-run cartoon episodes based on what year they were doing for that specific day I believe they aired cartoon episodes anywhere from 1957-1986 for example if they were showing cartoon episodes from the year 1962 it is very likely you'd see either Top Cat Flintstones or Jetsons, if they were showing cartoon episodes from the year 1959 it is likely you'd see either Huck Hound Quick Draw or Ruff & Reddy, if they were showing cartoon episodes from the year 1986 it is likely you'd see either Flintstone kids yogi's treasure hunt smurfs or snorks and so forth.
