When there's no more room in hell, the dead will walk the earth. And when there's no more AMC on Dish Network, the dead will walk New York City. Viral marketing agency Thinkmodo recently unleashed a small horde of zombies onto the streets to scare the bejesus out of pedestrians and, in the process, rally support for the Walking Dead network to be returned to Dish. The satellite provider blacked out AMC, IFC and Sundance a month ago  when programming fee negotiations went sour. Since we're still months away from the next season of Walking Dead, AMC needed a stunt like this to keep the super-popular show in people's minds. "Zombies don't belong here," Thinkmodo's video concludes. "Put them back on TV."
