On May 6, 2014, TSN announced that it would launch three new channels—TSN3, TSN4, and TSN5, in September 2014 to coincide with the network's 30th anniversary. TSN president Stewart Johnston described the expansion as an "important evolution" for the network, as it would allow TSN to make more efficient use of its portfolio of sports properties: the network promoted that these new channels would allow TSN to broadcast a larger amount of ESPN content and live events, particularly including expanded coverage of major events (such as Grand Slam tennis, curling tournaments, and the NCAA basketball tournament) with multiple games occurring simultaneously. Although the expansion was discussed by TSN staff as early as 2012, critics considered the loss of NHL rights to Rogers (which had recently launched its seventh Sportsnet-branded television service with its acquisition of The Score, now Sportsnet 360) to be a catalyst for the move, as TSN attempts to defend its position as the largest specialty television service in Canada in terms of total revenue.
