ι6 SCIENCE OF MASS COMMUNICATION
The growth of radio listening is another phenomenon of our time. The
first radio broadcast was made in 1920. Two years later it was estimated
that there were fewer than 500,000 families owning radio receiving sets,
but when the federal census made its first tabulation of radio set ownership
in 1930, the enumeration showed that 12,078,345 families possessed sets.
Something more than 35,000,000 families maintain homes in the United
States. Of these, 33,716,000 have radio sets, according to an April, 1944,
field study of the Bureau of the Census.
In 1900 there were no motion picture theaters in the country. The early
1900's saw the advent of the "nickelodeon." When the motion picture was
transferred to a stage screen, the response of the public was immediate. By
1910, about 9,000 theaters and other amusement places were exhibiting
pictures. The Motion Picture Division of the Department of Commerce
estimated in 1931 that there were 22,731 picture houses in the United
States, with an aggregate seating capacity of 11,300,000.30
Rosten reports81 that "there are 15,115 movie theaters operating in the
United States today—one movie theater for every 2,306 families, or for
every 8,700 Americans." And he adds: "There are more movie theaters in
the country than banks (14,952). There are twice as many movie houses as
there are hotels with fifty or more rooms (7,478). There are three times as
many movie theaters as there are department stores (4,201). There are
almost as many movie theaters as there are cigar stores and cigarette
stands."32
Available estimates of movie attendance are not wholly reliable. The
Hays office reported a weekly attendance of 40,000,000 in 1922. The 1930
estimate was ιοο,ΟΟΟ,ΟΟΟ. Reports for subsequent years follow: 1931,
90,000,000; 1932, 85,000,000; 1933, 80,000,000; 1934, 77,000,000;
1935, 87,000,000; 1936, 82,000,000; 1937, 85,000,000; 1941, 85,000,-

Consolidations in the Communications Industry
A second common tendency among the communication agencies is the
trend toward consolidations, standardization, and chain operation. In the
newspaper field there is a striking trend toward the elimination of com
petitive newspaper situations, especially in cities of fewer than 50,000 resi-

88 This 1943 total is at variance with the estimate made by Donald Slesinger, who reports
60,000,000; see "The Film and Public Opinion," in Print, Radio and Film, edited by Douglas
Waples. Rosten's estimate in 1941 is between 52,000,000 and 55,000,000.
8* These estimates take no account of age groups. It was estimated in 1940 that two-thirds of
those who visit motion picture theaters are under 30 years of age.
