For the Anime lineup, Cowboy Bebop and FLCL. In addition, back when it was new, Inu Yasha 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 it’s unlikely that a new show will premiere on this day.
Network Decay: Listed in Unique Situations. Contributing their part to Cartoon Network's decay (other than the Boston Bomb Scare), Adult Swim's lineup has been increasingly moving into both original and rerun live-action shows, along with a phase out of a number of animated shows and an increasing over-reliance on FOX Acquisitions for viewership and filling timeslots. Also mirroring main CN's decision of ending Toonami, the biggest victims of the decay has been the anime lineup, which has since been relegated exclusively to the Saturday Night-Sunday Morning timeslots. Adult Swim has however, called Cartoon Network's decay out and even lampshaded their own strange programming choices at times, so they're at least aware of this. Not to mention due to the same constant schedule switching that has screwed over many of its titles, what's decaying one week can be on the upswing the next.
