For example, the New York Rangers and New York Knicks have long co-owned their RSN, MSG; however, they also have purchased the rights to their rivals, the New York Islanders and New Jersey Devils. MSG also owns the rights to the Buffalo Sabres, however the team and ownership controls game production and that has since evolved into a separate MSG sub-channel for the Sabres market called MSG Western New York which is dual-controlled and programmed by MSG and Pegula Sports and Entertainment, owners of the Sabres effectively making it an owned and operated RSN. The Sabres once had their own owned-and-operated RSN before, Empire Sports Network, however instability in the Sabres and channel's ownership at the time led to difficulties and Empire was shut down in 2005 in favor of selling the Sabres' rights to MSG.
