a way to revitalize Showtime, either by launching a new tertiary pay service from scratch, or overhauling the format of Showtime sister network The Movie Channel. Incidentally, TCI made a failed bid to acquire a 50% ownership stake in Showtime in 1989. Encore had increased its subscriber base to an estimated 7 million subscribers nationwide by 1996. On January 1, 1997, Encore launched a new pay service called MoviePlex (originally named "Encore Plex" for its first few months on the air) which replaced a Liberty Media-owned network called INTRO Television, that ran blocks of programming from other cable channels. Until it adopted a separate film schedule on August 1, 2011, MoviePlex originally carried programming blocks from Encore's multiplex channels (which differed from that day's actual schedules for each channel to exclude R-rated movies) on a rotating day-to-day schedule. On June 2, 1997, TCI announced a deal in which it would transfer majority ownership of its Encore Media Group subsidiary to sister company Liberty Media, due in part to the significant profit losses incurred by Starz following that channel's launch – TCI retained a minority 20% ownership interest until its 1999 merger with AT&T Corporation, when Liberty Media assumed full ownership of the Encore Media Group.

By this point, Encore advertised itself as guaranteeing to air "a great movie every night", even setting up a special 1-800 number in which a $2.50 refund would be given to unsatisfied subscribers. Encore eventually began to be sold as a hybrid service, offered as either a premium channel or a digital basic network depending on the provider, retaining the uncut and commercial-free nature of its programming. Through this change in distribution, the channel was eventually available in 25 million homes nationwide by September 2005. On November 19, 2009, Liberty Media spun off Starz and Encore into a separate public tracking stock called Liberty Starz. On August 8, 2012, Liberty Media announced
