1989–90 United States network television schedule
From Wikipedia, the free encyclopedia
The 1989–90 network television schedule for the four major English language commercial broadcast networks in the United States covers primetime hours from September 1989 through August 1990. The schedule is followed by a list per network of returning series, new series, and series cancelled after the 1988–89 season.
Beginning this season, Fox started their prime time expansion starting with Mondays.
This is the first season to feature entirely closed captioning programs on the Big Four networks.
This was the first time that two programs were tied for the no. 1 spot in the Nielsen ratings.
PBS is not included; member stations have local flexibility over most of their schedules and broadcast times for network shows may vary.
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, Mountain, Alaska and Hawaii-Aleutian times.
Each of the 30 highest-rated shows is listed with its rank and rating as determined by Nielsen Media Research.[1]
