NBCUniversal to Shut Down Sports Network NBCSN at End of 2021 - Variety NBCUniversal will shutter its NBCSN sports network, and move some of its top sports properties to the USA network in a maneuver executives believe will boost the economics of the general-entertainment cable outlet at a time when new streaming-video hubs are luring bigger audiences. The decision could also push some sports fans to the streaming-video hub Peacock, which has begun to test new kinds of sports-programming opportunities. NBCU’s top sports properties include Nascar racing, National Hockey League contests and English Premier League football. USA is not going to become an all-sports network, this person cautioned, but might function more like WarnerMedia’s TNT, which has built a durable franchise out of its rights to air National Basketball Association games, does for that media company. It remained unclear whether the move would affect NBC Sports employees; the division recently experienced staffing cuts as part of a restructuring at NBCUniversal as it grapples with the economic fallout of the coronavirus pandemic.
