2004–05 United States network television schedule

The 2004–05 network television schedule for the six major English-language commercial broadcast networks in the United States covers the prime time hours from September 2004 to August 2005. The schedule is followed by a list per network of returning series, new series, and series canceled after the 2003–04 television season.

Beginning this season, largely resulting from continuing declines in prime time television viewership on that night of the week, the major networks ceased producing original scripted programs for broadcast on Saturday evenings (an exception being ABC's The Wonderful World of Disney, although it often featured rebroadcast material, mainly in the form of Disney theatrical films). From this point on, Saturday prime time network schedules would instead consist of nonfiction reality-based programs, rebroadcasts of scripted prime time series (most commonly featuring dramatic series), unaired episodes of de facto cancelled series that were being "burned off" after having been pulled from their previous timeslot on a different night, theatrical or made-for-television movies, and/or sporting events (which became increasingly common in the time period beginning with the 2012–13 season).

PBS is not included, as member television stations have local flexibility over most of their schedules and broadcast times for network shows may vary. Pax TV (now Ion Television) is also not included; although the network aired a few original first-run series, Pax's schedule at the time consisted primarily of syndicated reruns and movies.

Each of the 30 highest-rated shows released in May 2005 is listed with its rank and rating as determined by Nielsen Media Research.

New series are highlighted in bold.

Repeat airings or same-day rebroadcasts are indicated by (R).

All times are U.S. Eastern and Pacific Time, except for certain live events (such as Monday Night Football) that are broadcast simultaneously in all time zones. Subtract one hour for Central, Mountain, Alaska, and Hawaii–Aleutian times.

All sporting events air live in all time zones, with local and/or late-night programming (including those normally aired by Fox affiliates during the 10:00 p.m. ET/PT hour) being shown after the game's completion.

Note: The highest-rated television series of the year, American Idol, only aired in the winter and spring of 2005 and did not receive a berth on the fall 2004 schedule. The highest-rated regularly scheduled program, CSI, was colored on the schedule in yellow.--
