For the Anime lineup, Cowboy Bebop and FLCL. In addition, back when it was new, Inuyasha got favorable treatment with reruns and timeslots but also got the most mocked on the bumps, so hard to tell if they liked it at all or just liked the moolah it brought them. The Network Decay of Cartoon Network and Adult Swim has sent much of the Anime block towards the other direction however, to the point that some of their bumpers have stated (semi-seriously) that the above mentioned are the only good cartoons from Japan.
Friday Night Death Slot: Adult Swim was so afraid of this; they avoided airing shows on Friday for its first few years. They now show programs on Friday, although itís unlikely that a new show will premiere on this day.
On April 18, 2008, Adult Swim premiered Rising Son, a spoof of Soap Operas focusing on the life of Jesus), at 5 o'clock in the morning. Without any announcement of any kind except for the title appearing on the schedule.
Adult Swim will occasionally show a marathon of a show on April Fools just to do a Running Gag. At one time, an April Fools marathon of Perfect Hair Forever played all seven episodes in backwards order with bad subtitles. Another time, they showed the same episode of Harvey Birdman 24 times in a row.
On Christmas and New Year's Eve 2011, they showed all night marathons of Bleach.
Network to the Rescue: If a show that Adult Swim loves is having trouble, they will do everything in their power to save it. We didn't say Adult Swim loves to show love for shows that they adore for nothing, did we?
Adult Swim at one point started airing a promo in which they say Squidbillies has been getting low ratings... and how clearly the reason was that the viewers were morons and hadn't yet given this wonderful show a chance. That's why now they're airing it every single night instead of once a week, to get us to watch it and see how great it is.
Somewhat inverted with Tim & Eric Awesome Show, Great Job!. Adult Swim promotes the hell out of it and gives it gets the red carpet treatment, but the fanbase isn't biting and the show has low to middling ratings.
The Big O. The show was popular enough that Adult Swim is directly responsible for financing the production of the 2nd season. note It's also the reason why they only ever showed season 2 and not season 1: They own season 2. However, the premiere of the second season was around the same time Adult Swim begun its Network Decay, and they ended up screwing up the airing of a couple episodes (including accidentally airing a repeat over the finale) and ended up canceling the show before a reportedly expected third season, despite it having paid off financially. However, you could argue that this is more of Cartoon Network's fault considering that they were the ones that refused to fund the third season, perhaps due to the Network Decay that Cartoon Network was undergoing at the time.
Code Geass is a notable victim of Adult Swim's constant schedule switching of shows. Adult Swim had kept changing the time slot later and later to the point that people stopped caring and their rights to the show expired after one rerun.
Futurama, although this was from Fox rather than from Adult Swim. The DVDs sold more than Family Guy's, fan push was apparently larger, the ratings on Adult Swim were better, but Family Guy was the one that came back first. Also, Adult Swim even offered to fund new episodes and were told no. THEN the network got screwed over when the show they helped try to bring back was ripped away from them and given to another network. In this situation, it was Adult Swim that got screwed. On the bright side, the popularity and adoration it got from Adult Swim did help push for a continuation of the series on Comedy Central.
Korgoth of Barbaria, one of Adult Swim's most well received pilot shows, was supposedly green-lighted for an entire season, but aborted due to lack of funds that the higher ups refused to provide.
Adult Swim requested that the third season of Moral Orel to be as Darker and Edgier as much as creator Dino Stamatopoulos could make it. He complied, but after a screening of the darkest episode of the show's run ó "Alone" ó Adult Swim executives cancelled the series and cut Season Three down to thirteen episodes, which forced several key arcs to be abandoned. Be Careful What You Wish For indeed.
Moribito: Guardian of the Spirit was constantly schedule-switch later and later until it aired at 5:30 AM EST by Adult Swim, dropped after 10 episodes, restarted in a better timeslot, and then got dropped again after Geneon went bankrupt, and it was removed from the air until the licensing issues were resolved. However, the problems were eventually solved, and Adult Swim re aired and completed the series between June and December 2009.
The second season of Lucy, the Daughter of the Devil was canned after going through two years of Development Hell. A half hour second season was planned along with a new pilot, but both of which were scrapped due to Loren Bouchard and the network having creative disagreements about the show.
A second season of Stroker and Hoop was planned thanks to good ratings; including a series premiere that would have wrapped up the cliff hanger, but Adult Swim thought the show was far too pricey, and as a result, it was canned with no ending.
