On August 25, 2014, the primary TSN service was re-structured into four 24-hour feeds—TSN1, TSN3, TSN4, and TSN5—with each designated as the primary TSN network for each region of Canada. TSN now essentially operates as a group of regional sports networks similarly to Sportsnet, the 1, 3, 4, and 5 channels air some common programming and simulcast major events, while all five channels are capable of airing programming autonomously—including alternative national events and studio shows, supplemental coverage of larger events, and regional programming (such as NHL games; subject to blackout outside the respective team's market).
