1956–57 United States network television schedule

The following is the 1956–57 network television schedule for the three major English language commercial broadcast networks in the United States. The schedule covers primetime hours from September 1956 through March 1957. The schedule is followed by a list per network of returning series, new series, and series cancelled after the 1955–56 season.

The 1956–57 network television schedule continued the trend of the previous season, with two of the three major U.S. television networks (ABC and CBS) scheduling more and more westerns and adventure series during prime time. In addition to its current stable of Westerns, which included Cheyenne, The Lone Ranger, and The Life and Legend of Wyatt Earp, ABC scheduled two new Western TV series: Broken Arrow and The Adventures of Jim Bowie, while CBS added Dick Powell's Zane Grey Theatre to its line-up, which already included Gunsmoke and Sergeant Preston of the Yukon. Castleman and Podrazik (1984) called the rush to schedule Western series on network television during this era "a virtual stampede".^[1]

CBS "inherited Sunday afternoon NFL contests from the defunct DuMont network in the fall of 1956". Accordingly, "the expansion into Sunday sports by CBS (and NBC) meant that the traditional afternoon 'egghead' slots for highbrow programming had to be broken up, pushing those shows into the few odd spots still open in the day, or eliminating them completely. This reflected the networks' shift in emphasis during the mid-1950s, slanting television much more toward broad-based popular entertainment. Increasingly, this meant television programming produced in Hollywood [...] In 1957, the amount of prime time programming originating on the West Coast jumped from 40% to 71%."^[1] a change in no small part accelerated by the fact DuMont produced a large portion of its programming in Chicago and to a lesser extent Washington in addition to New York.

NBC, behind CBS in the network Nielsen ratings, hired Robert Kintner to revamp NBC's schedule. According to Castleman and Podrazik (1982), NBC's plan was to launch a program which would compete directly with CBS's second most popular series, The Ed Sullivan Show, on Sunday, the most heavily viewed TV night: "Sullivan's show was popular enough to boost the ratings of the programs on both before and after his; as a result, CBS had a chain of hits to begin the evening." NBC's strategy was designed to weaken CBS's Sunday night line-up. NBC's new program, The Steve Allen Show, debuted in the summer to get a head start on the competition.^[2] Although the two programs enjoyed a fierce rivalry, Sullivan's program would remain wildly popular, finishing second among all TV programs in the ratings that year, while Allen's show missed the top 30.^[3]

Beginning this season, NBC had at least one show in color for every day of the week.
