Popcorn Time (and its numerous forks) is a sort of dark rival to Netflix and other legitimate, licensed content streaming services. Essentially, Popcorn Time puts a simple interface over a BitTorrent backend. Once a user picks a movie to watch (and what resolution) it will torrent the content in the background and play it as it downloads.Now, a UK court has decided that ISPs in the union must block access to five websites associated with Popcorn Time, including popcorntime.io, flixtor.me, popcorn-time.se, and isoplex.isohunt.to.This order applies to Sky, TalkTalk, Virgin, BT and EE, who have previously been forced to block access to a large number of BitTorrent websites. The interesting difference in this case is those sites don't offer torrents or links to any pirated content, but instead offer downloads of Popcorn Time clients.
