Associated Press: Fans of shows based in the DC Comics universe like “The Flash,” ”Arrow” and “Gotham” might have to wait a lot longer for past seasons’ episodes to come to Netflix and Hulu. Jeff Bewkes, CEO of DC-owner Time Warner, said the company is considering whether to let online services like Netflix have its shows several years after they first air, rather than one year later. Withdrawing shows from online services would make traditional cable and satellite TV packages more attractive.
