Some shows never die on Twitter. For instance, every Wednesday, the 30 Rock Twitter account tweets: "What a week, huh?" "The internet is filled with ghost towns, haunted by forgotten GeoCities sites, Craigslist ads for apartments that have already been rented, and long-shuttered blogs that someone is still paying to keep online," says Olivia Craighead. "And yet there is a disturbing alternative, which can be found mostly on Twitter. I am speaking, of course, about active social media accounts for television shows that have not been on the air for years. These reanimated corpses continue to churn out content (mostly in the form of GIFs), presumably to get people to watch the show on whichever streaming service it calls home. I don’t know how effective this tactic is. I don’t think I would ever watch Parks & Recreation just because I saw someone engage with a picture of Rob Lowe taking a nap with a dog."
