NBCUniversal

NBC, formally known as the National Broadcasting Company, is the oldest major network in the United States. After a series of acquisitions, the network is now the flagship of NBCUniversal, which is a subsidiary of Comcast. As a broadcast pioneer dating back to the radio days of Jack Benny, NBC is responsible for a number of culturally significant programs, from The Tonight Show and Saturday Night Live to Friends and Seinfeld. The network is also well-known for its sports division, most notably the Summer and Winter Olympics and NFL games. NBC also has a strong news division, with NBC Nightly News consistently atop the evening news ratings.
