YouTube’s most popular channel, PewDiePie, hit a new milestone today, crossing 50 million subscribers. Promising to delete your channel, like announcing that you’ve decided to quit YouTube, or cancel your vlog, is not something most creators follow through on, at least not for good. PewDiePie is currently working on the second season of Scare PewDiePie, a produced web series that is available only to YouTube Red subscribers.
