The NHL on NBC is a presentation of National Hockey League (NHL) games that are produced by NBC Sports, and televised on NBC and NBCSN in the United States. While NBC has covered the league at various points in its history, the network's current relationship with the NHL is the result of NBC Sports acquiring the league's broadcast television rights from ABC in 2006. NBC's right to broadcast the league would expire in 2021 with ABC and ESPN taking the rights afterward. Since 2008, NBC's regular season coverage includes the annual NHL Winter Classic, an outdoor game usually played on New Year's Day; one national weekly regular season game each Sunday afternoon after New Year's Day; one week of regionally televised contests in February for Hockey Weekend Across America; and one nationally televised game on the day after Thanksgiving. NBCSN's coverage includes 90 regular season games that are mostly aired on Monday, Tuesday and Wednesday evenings (the latter dubbed Wednesday Night Rivalry), and later in the season on Sunday evenings. Coverage of the Stanley Cup Playoffs is split between NBC and NBCSN, with CNBC and the USA Network (beginning in 2015) airing selected playoff games during the first two rounds.
