Radio : Who Is Listening?
As early as 1929, the question of listenership was of interest to broadcasters and advertisers alike. That year Cooperative Analysis of Broadcasting (CAB), headed by Archibald M. Crossley, undertook a study to determine how many people were tuned to certain network radio programs. Information was gathered by phoning a preselected sample of homes. One of the things the survey found was that the majority of listening occurred evenings between 7:00 and 11:00 p.m. This became known as radio’s “prime time” until the 1950s. On the local station level, various methods were employed to collect audience data, including telephone interviews and mail-out questionnaires. However, only a nominal amount of actual audience research was attempted during the late 1920s and early 1930s. For the most part, just who was listening remained somewhat of a mystery until the late 1930s.
In 1938, C.E. Hooper, Inc. began the most formidable attempt up to that time to provide radio broadcasters with audience information. Like Crossley’s service, Hooper also used the telephone to accumulate listener data. CAB relied on listener recall; Hooper, however, required that interviewers make calls until they reached someone who was actually listening to the radio. This approach became known as the “coincidental” telephone method. Both survey services found their efforts limited by the fact that 40% of the radiolistening homes in the 1930s were without a telephone.
As World War II approached, another major ratings service, known as the Pulse, began to measure radio audience size. Unlike its competitors, Pulse collected information by conducting face-to-face interviews. Interest in audience research grew steadily throughout the 1930s and culminated in the establishment of the Office of Radio Research (ORR) in 1937. Funded by a Rockefeller Foundation grant, the ORR was headed by Paul F. Lazarsfeld, who was assisted by Hadley Cantril and Frank Stanton. The latter would go on to assume the presidency of CBS in 1946 and would serve in that capacity into the 1970s. Over a 10-year period, the ORR published several texts dealing with audience research findings and methodology. Among them were Lazarsfeld and Stanton’s multivolume Radio Research, which covered the periods of 1941–1943 and 1948–1949.
During the same decade, Lazarsfeld also published book-length reports on the public’s attitude toward radio: The People Look at Radio (1946) and Radio Listening in America (1948). Both works cast radio in a favorable light by concluding that most listeners felt the medium did an exemplary job. The Pulse and Hooper were the prevailing radio station rating services in the 1950s as the medium worked at regaining its footing following the meteoric rise of television.
In 1965, Arbitron Ratings began measuring radio audience size through the use of a diary, which required respondents to document their listening habits over a seven-day period. By the 1970s, Arbitron reigned as the leading radio measurement company, whereas Hooper and Pulse faded from the scene. To provide the radio networks and their affiliates and advertisers with much-needed ratings information, Statistical Research, Inc., of New Jersey, introduced Radio’s All Dimension Audience Research (RADAR) in 1968. The company gathers its information through telephone interviews with more than 6000 households.
In the 1990s, Arbitron retained its hold on first place among services measuring radio audiences, especially since the demise of Birch/ Scarborough, which gained considerable acceptance following its debut in the late 1970s. In 1991, this audience measurement company became yet another victim of the economic malaise.
Ratings companies must be reliable, and credibility is crucial to success. Therefore, measurement techniques must be tried and true. Information must be accurate, since millions of dollars are at stake. In 1963, the Broadcast Rating Council was established to monitor, audit, and accredit the various ratings companies. The council created performance standards to which rating services are expected to adhere. Those that fail to meet the council’s operating criteria are not accredited. A nonaccredited ratings service will seldom succeed. In 1982, the Broadcast Rating Council was renamed the Electronic Media Planning Council to reflect a connection with the ratings services dealing with the cable television industry.
Renamed the Media Rating Council (MRC) in 1997 to include Internet constituencies, the MRC’s declared purpose is (1) to secure for the industry and related users audience measurement services that are valid, reliable, and effective, (2) to avoid and determine minimum disclosure and ethical criteria for media audience measurement services, and (3) to provide and administer an audit system designed to inform users as to whether such audience measurements are conducted in conformance with the criteria and procedures developed.
