2015–16 United States network television schedule
The 2015–16 network television schedule for the five major English-language commercial broadcast networks in the United States covers prime time hours from September 1, 2015 to August 31, 2016. The schedule is followed by a list per network of returning series, new series, and series canceled after the 2014–15 season. NBC was the first to announce its fall schedule on May 10, 2015, followed by Fox on May 11, ABC on May 12, CBS on May 13, and The CW on May 14. PBS is not included; member stations have local flexibility over  most of their schedules and broadcast times for network shows may vary. Ion Television and MyNetworkTV are also not included since the majority of both networks' schedules comprise syndicated reruns (with limited original programming on the former). The CW is not included on weekends, since it does not offer network programming. New series are highlighted in bold. All times are U.S. Eastern and Pacific time (except for some live sports or events). Subtract one hour for Central and Mountain times. Note: From August 5 to August 21, 2016, all NBC primetime programming was pre-empted for coverage of the 2016  Summer Olympics in Rio de Janeiro, Brazil.
