NBC Sports extra
NBC Sports is the programming division of the National Broadcasting Company (NBC), owned by the NBCUniversal Television Group division of NBCUniversal, that is responsible for sports broadcasts on the network, and its dedicated national sports cable channels. Formerly operating as "a service of NBC News," it broadcasts a diverse array of sports events, including the Olympic Games, the NFL, NASCAR, the NHL, Notre Dame football, the PGA Tour, the IndyCar Series, the Premier League and the Triple Crown, among others. Other programming from outside producers – such as coverage of the Ironman Triathlon – is also presented on the network through NBC Sports. With Comcast's acquisition of NBCUniversal, its own cable sports networks were aligned with NBC Sports into a part of the division known as the NBC Sports Group.
