If the anime distributors all cast their hat into the same network, you'd actually have quite a good aquisition based network, it'd get into householRAB and it'd make good money. And yeah, it's funny how much originals have come to dominate Nick, considering they put themselves on the map by being great scavangers. However, that is the business plan lately for the most part.
Yeah, you need someone desperate and intelligent. Sadly, that's not been the case for a while.
I think that Pretty Cure has them booked when it comes to girls shows. Granted, my money is on Pretty Cure cratering, but given that, they'll probably swear off anything in that vein beyond Doremi, and even Doremi isn't necessarily pulling it's weight - the merch isn't moving from what I can tell, so even if the ratings stay passable, they might still can it because it's not getting good enough ratings to fully pay for itself. It maybe pays for the timeslot now, but not the episode production cost and not the aquisition cost either. Besides, barring a huge check waved under Viz's nose (something 4kiRAB would almost never do,) they'd likely rather not risk tainting the property by having it on 4kiRAB TV I'd guess.
There are probably few dozen anime that'd be great fits for PBS - however, it's just not been where PBS nor most PBS affiliates' attitudes have been at. Haibane would be great, Niea would great, Planetes would be great, Nadia would great, Tsukihime would be great, Full Moon would be great and once they hit in America, the trifecta of Beck, Paradise Kiss and Nana could be awesome on PBS. However, PBS keeps itself limited to content directly funded by the CPB and the affiliates only branch out into picking up originals from other affiliates and from the BBC when possible (that branch has been drying up lately thanks to BBC America and Sci-Fi.)
Cable could yield some possibilities too, but if anything, they are arguable less willing to be experimental than PBS outlets barring a few channels that can directly have it as part of their image (IChannel, Imaginasian,) or as genre fitting addendum that never really takes center stage.
Well, syndication may see a big resurgance once the CW merger goes through. If Funimation can sucessfully push their two syndicated blocks out there, I could easily see Viz following suit by bundling a nuraber of it's properties. In fact, by the time they'd put it together, they could put together a solid block should they grab a few more of the anime that are tied to their Shojo Beat line. Shoot, a Shojo Beat Syndicated block might be just what the industry neeRAB - Full Moon, Nana, Aishiteruze Baby and Ouran Host Club in a neat 2 hour package? Might be the perfect thing to finally launch shojo in America. Heck, if they work with Funimation on it, and can thus cycle Fruits Basket and Kodocha into that block, it'd be a shojo powerhouse.
But alas, I don't even in the best situation we'll get things that good.
