NASCAR on NBC

NASCAR on NBC is the brand name of NASCAR coverage on NBCUniversal-owned networks NBC, NBCSN, CNBC, and formerly (for 2016 only) USA Network. The networks have covered the final twenty races of the NASCAR Cup Series and the final nineteen races of the NASCAR Xfinity Series since 2015. NBC properties also covered the Cup Series and Xfinity Series in conjunction with TNT from 2001 to 2006, with NBC also airing the Ford EcoBoost 400 at Homestead in 1999.

2001-2006: NBC, TNT
On November 11, 1999, NASCAR announced a new centralized, television deal between NBC and Fox for Nextel Cup Series (now Monster Energy Cup Series) and Busch Series (now Xfinity Series) telecasts from 2001 to 2006. Fox and its cable network FX would broadcast the first half of the season, while NBC would broadcast the second half. Fox and NBC would swap coverage of the Daytona 500 and Pepsi 400 (now Coke Zero Sugar 400), with Fox broadcasting the 500 in odd-numbered years, while NBC covered the 500 in even-numbered years. NBC partnered with Turner to assist NBC in broadcasting races. Turner originally planned to put NASCAR races on TBS, which had aired races since 1983 but moved the races to TNT prior to the start of the season. NBC would broadcast the majority of Cup events, while TNT would broadcast the majority of Xfinity events. The qualifying and practice sessions would mainly air on Comcast SportsNet and TNT, with a few, select sessions of Fox-owned Speed. When it came time to negotiate a new deal in 2006, NBC declined to renew its package. TNT, however, decided to split from NBC, taking most of NBC's crew with it, and obtained rights to six mid-season races, including the Coke Zero Sugar 400, through 2014. ESPN picked up rights to the remaining NBC races, while Fox renewed its contract.

2015-present: NBC, NBCSN
On July 23, 2013, NBC announced a new television deal with NASCAR to return broadcasting events in 2015 after an eight-year absence. NBC would obtain rights to the final 20 NASCAR Cup Series races and the final 19 NASCAR Xfinity Series races. Instead of hooking back up with former partner TNT, which lost rights, as a result, NBC chose its cable sports network NBCSN, which became a part of NBC in 2012, as its cable partner. Unlike the 2001-2006 arrangement, NBCSN will cover almost all events, with NBC covering only a select few events. In the NASCAR Cup Series, NBC will broadcast seven events, while NBCSN will broadcast thirteen. In the NASCAR Xfinity Series, NBC will broadcast four events, while NBCSN will broadcast fifteen. New under the deal, NBC will pick up exclusive rights to the K&N Pro Series and Whelen Modified Tour series, in addition to NASCAR Hall of Fame telecasts. NBC made its preliminary return in 2014, broadcasting a daily NASCAR-themed show NASCAR America and broadcasting the Mexico Series season opener at Phoenix Raceway on its Spanish cable network mun2 (now NBC Universo). NBC made its official return in early-2015, with a K&N Pro Series East telecast from New Smyrna Speedway in Florida.

2016: CNBC, USA
In 2016, due to NBC's coverage of the Summer Olympics, sister channels CNBC and USA Network aired races. The USA channel broadcast the Cup Series race at Watkins Glen International and a pair of Xfinity Series races at Mid-Ohio Sports Car Course and Bristol Motor Speedway, while CNBC solely aired the NASCAR Xfinity Series race at Watkins Glen.

In 2020, the Cup Series will take two weeks off to minimize any conflict with the Olympics; the Michigan race will be run on the day of the Games' closing ceremony. The two Xfinity Series races that will take place during the Games (at Iowa and Road America) will air on CNBC. If a NASCAR race is postponed to Monday and it conflicts with an English Premier League match, the race will move to USA (CNBC is also unavailable on weekdays due to its stock market coverage), though this has not happened yet as of the end of the 2019 season.
