Cartoon Network's Adult Swim block is winning the 12-24 male demographic group against all other programming in its time slot, cable or broadcast.  Ratings have been improving since the switch to five nights a week (see 'Cartoon Network Ratings Up') and the Adult Swim programming is now beating Leno by 18%, Letterman by 82%, Conan by 26%, and the other competition by greater margins in that demo, with triple the viewers in that group vs. Craig Kilborn at the most extreme.  The block currently includes four anime series:  Lupin the 3rd, Inu Yasha, Trigun, and Cowboy Bebop, all of which have significant product associated with them.
