From 1998 to 2001, CN's promo department skewered modern sports telecasts- and especially the Super Bowl- by broadcasting The Big Game; each year featured a bunch of shorts with classic rivalries edited together to seem like a football game. And each year, it ramped up in absurdness and parodies. 1998, with Tom vs. Jerry, was fairly simple. But the 1999 matchup, Sylvester vs. Tweety, really took things to a new level- corporate cousin HBO loaned out the crew at the time from Inside the NFL to make a fake pregame show; also added to the mix were fake commercials and an Acme Corporation-sponsored halftime show. 2000 took it even further- in addition to fake commercials for the Robotic Way, Wayne Enterprises and Spinach, and a bungled Spacely Sprockets halftime show (we ended up seeing Fred and Moltar manning master control for 10 minutes, but the pregame show was now backed by the Slate Rock and Quarry Co., and John Madden and Pat Summerall were the main commentators, with Bubba Smith and Scott Hamilton as the sideline guys at Chuck Jones Stadium. Not only that, but the scripts were peppered with parental bonuses galore (ie. referencing how they had started telecasting "Desert Division" games back in October of 1999- when CN finally nabbed the rights to the Wile E/RR Toons from Nickelodeon). Not only that, but the late great Harry Kalas voiced a recap of the previous Big Game, and even a "Look Back" special on the other Big Games was produced. 2001 and Bugs vs. Daffy saw the return of the Inside the NFL crew, plus Harry Kalas; supplementing it was a tailgate party on Cartoon Cartoon Fridays. Unfortunately, it came to and end after that, but the CN promo dept. did their absolute best to parody everything people take for granted in sports coverage and the Super Bowl, and yet make it so serious.
There were no shortage of cheers when Cartoon Network eventually dropped the last of their live-action programming and fully returned to animated programming. Despite the network now playing favorites to Ratings-friendly, Moral Guardians-pandering, and Executive-appealing shows at the expense of their more critically-acclaimed work, along with the occasional live-action movie, it was reassuring that Cartoon Network, rather than playing catch-up with Nickelodeon and Disney Channel, stuck to what they were best at: Being "the best place for cartoons".
Managing to sneak in Screwy Squirrel on April Fools Day 2012, marking the return of Tex Avery cartoons since 2002.
Toonamiisback. It's still only on Saturdays (essentially being a replacement/revamp for [adult swim]'s Action block) and run by a small, dedicated staff, but now the block is able to air programs that would have been heavily censored had it remained on the kid-oriented Cartoon Network. Even though the block primarily airs adult-oriented anime, an ultra-niche format that isn't appealing to advertisers, it has gotten a ton of support from people other than nostalgia-driven fanboys. Not to mention, outside of Disney XD, Toonami (and by extension, Adult Swim) is still the only outlet on TV that is willing take a chance on mature, action-oriented, non-comedic, animated programming. Between Cartoon Network's cruel treatment of shows that aren't ratings-driven, slapstick comedies, and Adult Swim as a whole de-emphasizing animation in-favor of being a general comedy network (and their general Love-Hate relationship with anime), this is really something to appreciate.
What the network did on its 20th birthday, October 1, 2012. It ran birthday-themed episodes of their favorites past and present, an original music video featuring over 100 characters, the 100th episode of Adventure Time and a special half-hour Regular Show.
Big Bag, a show produced by the Childrens Television Workshop produced episodes for Cartoon Network from June 1996 to June 1998. One of the episodes featured Elmo from Sesame Street as a pen pal of the main character as seen here. Now that's just awesome!
On October 13, 2017, Cartoon Network had a little ghost possessing your TV that changes New New New New promos into channel changes, creating spooky puns like changing Teen Titans Go! to Teen Titans Ghost!, Changing dance sequences to x-ray skeletons, and of course, switching voices.
