When does NASCAR on NBC return?

NASCAR on NBC is the branding used for broadcasts of NASCAR races that are produced by NBC Sports, and televised on several NBCUniversal-owned television networks, including the NBC broadcast network in the United States. The network originally aired races, typically during the second half of the season, from 1999 to 2006. On July 23, 2013, NBC signed a new agreement with NASCAR to obtain the rights to races from the NASCAR Cup Series, NASCAR Xfinity Series, ARCA Menards Series East and NASCAR Whelen Modified Tour seasons starting in 2015.
