The 1951–52 United States network television schedule began in September of 1951 and ended in the spring of 1952. This was the first television season of national network interconnection by coaxial cable and microwave, meaning programming could be transmitted live coast-to-coast (or in the case of filmed programs, distributed simultaneously across the country) if needed.
On Sunday nights, NBC experimented with airing its new comedy-variety program Chesterfield Sound-off Time (featuring Bob Hope, Fred Allen and Jerry Lester as rotating hosts) in an early evening timeslot, 7:00–7:30. Previously, network TV variety programs had only been aired during late evening hours. According to television historians Castleman and Podrazik (1982), the experiment was designed to "duplicate the early-evening radio success of Jack Benny". (Benny himself would appear on rival network CBS's The Jack Benny Program immediately following Chesterfield Sound-off Time). Red Skelton also made his network television debut on NBC's Sunday night schedule this season, but long-term success eluded him until after he moved to CBS in the fall of 1953.
Although most TV programming was live, both CBS and NBC also experimented in filmed series; Castleman and Podrazik highlight early filmed hits I Love Lucy on CBS and Dragnet on NBC. Dragnet was "one of NBC's first major experiments in filmed TV series"; the series was added to NBC's regular network schedule in January 1952, after a "preview" on Chesterfield Sound-off Time in December 1951. I Love Lucy was given what historians have called a "choice time slot": Monday night immediately following the number one program on television: Arthur Godfrey's Talent Scouts. The series "proved the strength and acceptability of TV sitcoms, giving [CBS] a strong weapon against NBC's flashy comedy-variety hours".
DuMont, too, avoided flashy comedy series when in February 1952, in desperation the network added Bishop Fulton Sheen's program, Life Is Worth Living, to its Tuesday night schedule. The religious series was pitted against NBC's hit program Texaco Star Theater, and became the surprise hit of the year, holding its own against Texaco host "Uncle Miltie", and attracting a sponsor, an Emmy, and 10 million viewers. The ABC and CBS programs which aired in the same time slot, Charlie Wild, Private Detective, and The Frank Sinatra Show (respectively), attracted relatively few viewers.
New fall series are highlighted in bold. The highest-rated show for the year is colored in gold, the second-highest appears in silver, and the third-highest in bronze. Each of the top 30 highest-rated shows is listed with its (rank/rating) as determined by Nielsen Media Research.
