The 2023–24 network television schedule for the five major English-language commercial broadcast networks in the United States covers the prime time hours from September 2023 to August 2024. The schedule is followed by a list per network of returning series, new series, and series canceled after the 2022–23 television season. The schedule was affected by strikes undertaken by the Writers Guild of America (which began on May 2 and ended on September 27) and SAG-AFTRA (which began on July 14 and is still ongoing). Programming impacts on the 2023–24 season itself were limited in comparison to previous television seasons affected by Hollywood labor disputes.
CBS was the first to announce its initial fall schedule on May 10, 2023, via press release (without an upfront presentation). However, as a result of the ongoing strikes, a revised schedule for CBS was released on July 17 (with its premiere dates announced on August 3). This was followed by NBC, which also announced its initial schedule on May 12 (with their upfront presentation at 11 a.m. Eastern Time on May 15), but later announced its revised schedule on July 19 and August 29 (along with the premiere dates), and ABC which announced its initial schedule on May 16 (with their upfront presentation at 4 p.m. that day) but later announced part of its revised schedule (along with its premiere dates on August 21), with its Tuesday and Monday schedule (along with its premiere dates) on September 12 and 18 respectively. The CW announced its initial fall schedule on May 18 (their upfront presentation of the original schedule was held at 11 a.m. that day), before it was revised on June 6 with the release of its summer schedule for the previous season, and its replacement programming was announced on July 12 (along with their premiere dates). Fox announced its programming on May 15 via press release that morning (with their upfront presentation at 4 p.m. that day), but released its Sunday schedule (along with its release dates) on July 10, along with the rest of its prime-time schedule (which was revised due to the strike, however its original schedule wasn't announced) (with their premiere dates) on July 11.
PBS is not included, as member television stations have local flexibility over most of their schedule and broadcast times for network shows may vary. Ion Television and MyNetworkTV are also not included since both networks' schedules consist of syndicated reruns and live sports.
Each of the 30 highest-rated shows releasing in May 2024 is listed with its rank and rating as determined by Nielsen Media Research.
Beginning this season, The CW began airing encores during the first hour of primetime on Sundays.
Impact of the 2023 Writers Guild of America and SAG-AFTRA strikes
On May 2, the Writers Guild of America went on strike, followed by SAG-AFTRA on July 13. The absence of working writers and actors through the summer has led scripted television production to shut down completely. The Writers Guild of America strike ended on September 27, while the SAG-AFTRA strike is still ongoing.
Network schedules were heavily altered in response to these strikes. The vast majority of new or returning live-action scripted series on the broadcast networks were not scheduled to premiere until, or have been delayed until, 2024. Reality television and game shows are slated to fill many gaps in programming, as SAG-AFTRA members are permitted to work on such productions during the strike.
However, the networks took slightly different strategies for parts of their schedules. In anticipation of the potential strikes, NBC delayed drama series Found, which was originally intended to air as a mid-season replacement in the 2022–23 season, to fall 2023, while also fast-tracking the production of other scripted series such as the second season of Quantum Leap and the premiere season of The Irrational.
CBS will repurpose series originally produced for sibling properties, including episodes of Yellowstone, which originally aired on the Paramount Network, SEAL Team, which originated on CBS before moving to Paramount+, FBI True, which was also produced for Paramount+, and NCIS: Sydney, an Australian spin-off of NCIS originally intended for sister property Network 10 and Paramount+ before being added to the CBS schedule as well. Episodes of Ghosts, the BBC series on which an American adaptation was based, have also been added to the CBS schedule.
