So, would one say these are the points of marking transition periods for Cartoon Network:
2001: Shows from Kids WB begin airing on the network.
October 2004: The point where Cartoon Network removed both the Boomerang block (aka the only source for the non-Scooby Doo Hanna Barbara cartoons) and the Looney Tunes shorts, with most of the pre-2004 original series (except Ed, Edd, n Eddy, The Grim Adventures of Billy and Mandy, and Codename Kids Next Door) ending production at this point. Also the year they introduced the new logo and rebranded.
June 2008: Point where the pre-2007 Cartoon Network originals ended production and stopped airing premieres on a weekly basis (with Ed, Edd, n Eddy, Grim Adventures of Billy & Mandy, Foster's Home for Imaginary Friends, and My Gym Partner's a Monkey's final episodes either being aired as TV movies or several episodes being burned off in one day). Also when the defining shows of the 2008-10 era showed up with Flapjack, Ben 10 Alien Force, Secret Saturdays, and the Canadian cartoons such as Total Drama, 6teen, and Johnny Test. Premieres for the non-action cartoons also move from Friday to Thursday
September 2010: Point where the 2007-09 Nood era shows wrapped up aside from Johnny Test and Total Drama. Also this and 2011 introduced a TON of new shows. Premieres for the non-action shows move from Thursday to Monday. Also a rebranding and new logo.
February 2012: Cartoon Planet launches and premieres for action shows move from Friday nights to Saturday mornings. The non-action cartoons also stop premiering exclusively on one day and are split among various days now.
Summer 2014: The pre-2010 original series stopped airing regularly and premieres of all non-action shows move to Thursdays again.
2015: Teen Titans Go dominates the schedule and Adventure Time and Regular Show's airtime decreases hard.
2021: New president for the network and Cartoonito launches. Original programming from Cartoon Network slows down at this point.
