The 2006–07 network television schedule for the six major English language commercial broadcast networks in the United States covers the prime time hours from September 2006 to August 2007. The schedule is followed by a list per network of returning series, new series, and series cancelled after the 2005–06 season.
The schedules include the four most popular networks (CBS, ABC, NBC, and Fox) and two new networks introduced as part of the broadcast TV realignment: The CW and MyNetworkTV.
PBS is not included; member stations have local flexibility over most of their schedules and broadcast times for network shows may vary. Ion Television (renamed from its original rebrand, i: Independent Television, on January 27) is also not included since the network's schedule consisted mainly of syndicated reruns and movies.
Each of the 30 highest-rated shows released in May 2007 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 some live sports or events). Subtract for one hour for Central, Mountain, Alaska and Hawaii–Aleutian times.
All sporting events air live in all time zones in U.S. Eastern time, with local and/or late-night programming (including Fox affiliates during the 10 p.m. ET/PT hour) by affiliates after game completion.
