• The sports network, which was rebranded in 2011, will move its NHL, NASCAR and Premier League rights to USA Network, which is also owned by parent company NBCUniversal.

The NBC Sports Network is shutting down.

The network will stop operations by the end of 2021, a person familiar with the plan confirmed to CNBC. NBC will transfer its sports media rights, including the National Hockey League, to USA Network. The person spoke to CNBC on condition of anonymity as the individual isn’t allowed to comment publicly on the matter. Both networks are owned by CNBC parent company NBCUniversal.

The plan to halt operations will allow NBC to attract more reach for its sports content. USA Network is available in 86 million homes, while NBCSN has an estimated 80 million household reach.

This will not impact the NBC Sports regional networks, which include NBC Sports Boston, NBC Sports Philadelphia, NBC Sports Washington, NBC Sports Chicago, NBC Sports Bay Area and NBC Sports Pacific Northwest. These regional sports networks operate as a separate business from NBC Sports Network.

NBCUniversal initially hoped NBC Sports Network would be its response to Disney’s ESPN -- a cable sports network that could justify high affiliate fees from pay-TV distributors because of its popular sports content. Twenty-first Century Fox developed Fox Sports 1 and CBS introduced CBS Sports Network for similar reasons.

But none of the cable sports networks have ever seriously threatened ESPN, and the media industry’s move toward streaming video has made linear sports networks anachronistic. NBCUniversal is considering shutting down several networks, CNBC reported in October, to consolidate its best assets in fewer networks. Shuttering underperforming cable networks could allow legacy media companies to keep the shrinking cable bundle afloat while maintaining subscription revenue by boosting fees for its existing networks.

The network started in the 1990s as the Outdoor Life Network, then was rebranded to Versus in 2006. Comcast owned the network when it took over NBCUniversal in 2011, and rebranded it as the NBC Sports Network at that time.

NHL playoff games, a selection of NASCAR races, and Premier League content will transfer to USA Network after NBCSN closes.

The Stamford, Connecticut-based network took over NHL rights with a 10-year, $2 billion package in 2011. The agreement runs through the current 2020-21 season.

NBCSN also has a $4.4 billion rights package with NASCAR that expires in 2024 and coming up on its renewal option with European’s soccer Premier League rights (worth roughly $1 billion). The network moved some of those games to NBC’s streaming service, Peacock, last year.

Back to the future

Longtime sports media rights advisor Lee Berke said the move is “back to the future” for USA Network airing sports content. The channel was originally a national distribution arm for Madison Square Garden Sports Network, airing sports content including the National Basketball Association until 1984.

“The fact that sports is returning to USA isn’t a new concept,” Berke told CNBC in an interview on Friday. “Certainly the distribution is helpful but this move is reflective of a couple of things -- the pay TV bundle is shrinking. Subscriber base is shrinking. So, it justifies fewer networks to be on the air and the other part of it is the growth of streaming.”

Berke, the CEO of LHB Sports, a sports consultancy firm, said streaming trends is forcing network to reinvent themselves “as consumer viewing behavior changes. The was a migration of sports from broadcast to cable over the past 20, 30 years when pay TV became bigger and bigger. And now you’re seeing sports migrating to streaming.

“I think its a sensible move given the trends that are taking place,” said Berke of NBCSN’s closure. “You’re trying to stay ahead of the wave. You don’t want to be behind it and miss out. But this makes sense based off where pay TV is heading and base on where streaming is heading.”
