On May 6, 2014, TSN announced plans to launch three additional multiplex channels, for a total of five 24-hour national channels. The existing "TSN" service was replaced by four regionally-focused channels (referred to as "feeds")—TSN1, 3, 4, and 5—similar to the Sportsnet regional channels. All five channels are available nationally, but on most local providers, the channel location previously occupied by TSN's primary service was filled by the appropriate regional feed. While major sports telecasts are simulcast across TSN1, 3, 4, and 5 to ensure national coverage, alternative studio shows and live events can also be split across the channels. The feeds carry a small amount of programming tailored towards their respective regions, including simulcasts of lunch-hour shows from TSN Radio stations in their relevant region, and regional NHL coverage. When TV listings and promotions make a reference to a program airing on "the TSN network" or simply "TSN" without disambiguation, it can normally be assumed that the program will be simulcast on TSN1, 3, 4 and 5.
