simpsons are still a thing in 2015, crazy
Technically, everything is still a "thing" when you look at it, what with nostalgia-laden merchandise and reruns. Gumby even plays on a station around here, and the last time he mattered was when they made a (TV, I want to say?) movie about him.
But that doesn't mean they're still relevant, far be it. They only survive by leeching onto other things' popularity too late for it to be notable. Watch, the season 2 years from now will feature Lorde and a Couch Gag about how a shirt can be seen multiple ways.
