Warner Brothers and DC Comics have so many live action and animated translations of their comics, it seems to me to make perfect sense to create a new broadcast network to showcase them. As far as content, it would be highly profitable to WB due to the fact they own all the properties. They could easily run animated series from 7 to noon, and then run live action series from noon to 8pm. For instance you could start with 2 episodes of Smallville at noon, followed by an hour of The Adventures of Superman, Superboy for an hour, Lois & Clark, Wonder Woman, an hour of Batman, and Arrow winding up at 7pm. At 8pm weeknights, you could show a 2 hour block of short lived series such as The Flash (1990), Human Target, Witchblade, and Man From Atlantis (though not comic book, would fit in the general programming demographic). In the overnight hours, you could re-air the shows from noon to 8pm, this time from 10pm to 6am. That would only leave one hour of no programming block, where you could run paid programming or meet E/I requirements.
On the weekends, you could run movies and other short-lived series, such as iZombie, Constantine (if neither gets picked up for a second season), Birds of Prey, and the first seasons of Gotham and The Flash from The CW. They could also run late night shows on Saturday with Blade The Series (as WB owns New Line Cinemas, but iffy since it is a Marvel character) and Spawn from HBO.
As revenue grows on the network, they could start adding other series and film rights to broadcast as well as original programming. The first original program should be DC All Access every week for an hour show. They already produce it online, so it would not be difficult to stretch to an hour with ads, plus this would give lengthier segments and interviews and the reports would not have to be so rushed. They could also air a show that truly delves into the different characters. A half hour documentary style would be perfect for this show. As funds grow, new animated and live action series could also be developed.
Other shows that would fit in the realm of the network would be Dark Angel, Misfits of Science, My Secret Identity, Powers of Matthew Starr, Heroes, Painkiller Jane, Flash Gordon, Black Scorpion, The Greatest American Hero, The Green Hornet, and so on. They could also consider acquiring broadcast rights of Marvel shows such as The Incredible Hulk, Spider-Man, Nightman, and Mutant X as well as the animated and new series from Marvel Studios. They could also try to acquire rights to Comic Book Men reruns.
In other words, there is so much potential to launch a successful network centered around the comic book characters we all know and love. Hopefully, one day soon, WB will finally realize the goldmine they have in broadcasting these shows again and we will all win for it. After all, if networks devoted to Golf, Football, wrestling, and so on reach an audience for year round viewing, surely the entertainment provided by comic based shows and films would also generate plenty of interest...
