Movie4k.to, formerly known as Movie2k.to, is a user-contributed video directory for television programs and films. It is an aggregation-website acting as a search index for online videos. In May 2013, Movie2k.to was shut down by the Motion Picture Association of America (MPAA) due to copyright infringement concerns, but morphed into Movie4k.to shortly after. It primarily serves English and German-speaking areas.
