In the spring of 1936, Arthur C. Nielsen encountered a device that could record when a household radio was in use and which station it was tuned to. The device, called the Audimeter, had been developed by other researchers. Nielsen acquired the technology and its rights, and his company spent years adapting it for commercial audience measurement.
By December 1942, the firm had launched a radio ratings service. National television measurement followed in the early 1950s. Yet Nielsen’s route to broadcasting began in a very different line of work: testing how industrial machines performed.

From a Chicago Engineering Career to His Own Firm
Arthur Charles Nielsen was born in Chicago on September 5, 1897. He studied electrical engineering at the University of Wisconsin and graduated summa cum laude in 1918. During the World War I period, he also served in the U.S. Naval Reserve. That year, he married Gertrude B. Smith.
After college, Nielsen worked as an electrical engineer for the Isko Company from 1919 to 1920 and for H. P. Gould Company from 1920 to 1923. His first independent venture would also begin in engineering, far from the consumer and broadcast research for which he became known.
In 1923, he founded the A. C. Nielsen Company in Chicago. Incorporated on August 24, the firm started with approximately six employees and about $45,000 raised through former college fraternity associates. Its early assignments tested the performance of machinery such as conveyors and turbines. It later expanded into industrial market surveys, with a company chronology identifying a first such survey in 1927.
When Industrial Testing Was No Longer Enough
The Great Depression reduced demand for manufacturing-related work and pushed Nielsen’s young firm into serious financial difficulty. The industrial surveys on which it had relied could no longer sustain the business as before.
Nielsen redirected the business toward consumer sales research. Rather than concentrating on how equipment operated, the company began developing ways to measure how products moved through stores. A pharmaceutical client project in 1931 preceded the recurring Nielsen Drug Index, introduced in 1933. Food and department-store indexes followed in 1934.
Instead of isolated performance studies, the company now offered continuing reports that let manufacturers follow changes in product sales over time.
Turning Store Shelves into Comparable Sales Data
Nielsen’s retail indexes drew on carefully selected panels of food and drug stores. Investigators made repeat visits, checked purchase invoices, and examined stock on shelves. From those observations, the company estimated product movement and compared brands across markets.
A manufacturer could already study its own shipments. Store-level audits offered a different view: how its products compared with competing brands at retail. Repeating the surveys let clients track estimated sales movement and market share from one period to the next.
Nielsen and his company became closely associated with the use and popularization of the term market share. His larger achievement was not the invention of all market research, but the development of recurring commercial measurements that companies could use when evaluating marketing and distribution.
Buying the Audimeter and Building a Radio Ratings Service
The next opportunity came from clients who also spent money on radio advertising. They wanted evidence about broadcast audiences comparable to the information they were already getting about retail sales.
At a 1936 presentation, Nielsen learned about radio-tuning recorders. Robert Elder and Louis F. Woodruff had developed an Audimeter at the Massachusetts Institute of Technology, while Claude Robinson had developed a related recorder independently at Columbia. Nielsen acquired the devices, patent rights, and Audimeter trademark. He was an important developer of their commercial use, not the original inventor.
The early meter attached to a household radio and recorded set operation and station tuning on film. Company personnel retrieved the records and sent them to Chicago for processing. Equipment costs and collection work made the approach difficult to operate on a large scale.
After several years of testing and modification, the Nielsen Radio Index entered commercial service in December 1942. A competing ratings provider, C. E. Hooper, used telephone-based audience surveys. Nielsen’s meters offered a different method: the sampled household did not need to have a telephone for its receiver to be recorded.
In 1946, the company introduced a mailable Audimeter, reducing the need for staff to retrieve records directly from every home.
From Radio Competition to Television Ratings
By the end of the 1940s, Nielsen was extending the logic of radio measurement to television. In 1950, the A. C. Nielsen Company acquired C. E. Hooper’s national radio and fledgling television ratings operations, strengthening its position in national audience research. The purchase did not include all of Hooper’s local radio operations.
Nielsen’s corporate history dates the beginning of its national television audience measurement to 1950. In 1954, the company added the Nielsen Station Index for local television markets.
Ratings gave advertisers and broadcasters a way to compare programs and markets, evaluate audience reach, and plan or price advertising. The estimates also influenced programming decisions. Their commercial importance, however, did not make them exact headcounts of viewers.
A basic meter recorded whether a radio or television set was operating and which station it received. That did not establish who was watching or listening, whether anyone paid attention, or how an advertisement was received. Diaries and other methods helped supply information the tuning records could not capture.
International Growth and a New Generation of Leadership
The move into television came after the business had begun expanding beyond the United States. The company opened a United Kingdom office in 1939, established operations in Canada in 1944, and entered Australia in 1948.
Arthur C. Nielsen Jr. joined the firm in 1945 and succeeded his father as president in 1957. Nielsen Sr. remained in a senior founder and chairman role, while the younger generation assumed responsibility for leading the business.
The company began offering shares to the public in 1958. Nielsen Sr. received a Danish knighthood in the Order of Dannebrog in 1961 and the Charles Coolidge Parlin Memorial Award in 1963.
When the Ratings Business Came Under Scrutiny
As audience estimates gained influence, questions about how they were gathered became more consequential. Critics examined the representativeness of household samples, whether people cooperated reliably with diaries and meters, and how much confidence advertisers and broadcasters should place in figures drawn from relatively small groups.
U.S. House hearings in 1963 investigated ratings methods and industry practices. They were separate from a Federal Trade Commission proceeding concerning the competitive conduct of the A. C. Nielsen Company.
On October 23, 1963, the FTC entered a consent order involving the company. Its complaint alleged restrictions on competition in national audience measurement, including issues involving the relationship with Hooper and competing measurement technology. The order imposed restrictions on certain arrangements and acquisitions and addressed access to measurement technology through licensing.
The company agreed to the order for settlement purposes without admitting the complaint’s substantive allegations. The proceeding was not a trial judgment establishing every charge, and it did not constitute a finding of personal wrongdoing by Arthur C. Nielsen Sr.
During 1963–1964, the company also withdrew some radio measurement services amid technical difficulties and changes in station choices and listening habits. This retreat involved challenges beyond the FTC proceeding and occurred under the younger Nielsen’s presidency.
Tennis and a Life Beyond Market Research
Long before Nielsen became known for audience ratings, he had captained the varsity tennis team at the University of Wisconsin. Tennis remained part of his life well beyond his student years.
Nielsen and his son Arthur Jr. won U.S. father–son doubles titles in 1946 and 1948. Nielsen and his wife later helped fund the University of Wisconsin’s Nielsen Tennis Stadium, built in 1968. He was inducted into the International Tennis Hall of Fame in 1971.
In 2005, former employee Gale Metzger recalled Nielsen Sr. during testimony to a U.S. Senate committee: “I knew him as a kind and intellectually generous person.” It was Metzger’s personal assessment, offered years after they had worked together.
Arthur C. Nielsen Sr. died in Chicago on June 1, 1980, at age 82. Further recognition followed: he was named to the Advertising Hall of Fame’s class of 1987 and entered the University of Wisconsin Athletic Hall of Fame posthumously in 1992.
A Legacy in Measurement—and Its Limits
Nielsen’s lasting contribution was to make comparisons of retail sales and broadcast audiences available as recurring commercial information. Manufacturers could evaluate their brands against competitors, while broadcasters and advertisers could make decisions using audience estimates.
A company retrospective described the original Nielsen Code with four principles: “impartiality, thoroughness, accuracy, integrity.” Those aspirations existed alongside recurring questions about sampling accuracy and competitive practices—issues that also shaped the company’s history.
The company was sold to Dun & Bradstreet in 1984, after Nielsen’s death. In 2021, the consumer-goods measurement business became the separate NielsenIQ enterprise, while Nielsen continued as a media-measurement company. The names now refer to distinct businesses with a shared historical origin.
From machine testing to store audits and audience ratings, Nielsen helped make repeated measurement central to business decisions. His work also illustrates the distinction between a useful estimate and a complete count of everyone or everything being measured.

FAQs
Question: Did Arthur C. Nielsen invent the Audimeter?
Answer: No. The original recording devices were developed by other researchers. Nielsen acquired the Audimeter devices and rights in 1936 and helped turn the technology into a commercial radio ratings system that launched in 1942.
Question: What did the original Nielsen ratings actually measure?
Answer: The electronic meters recorded when a sampled household’s radio or television set was operating and which station it was tuned to. Estimates were extrapolated from the sample. A tuning record alone could not identify every individual audience member or establish whether anyone paid attention; diaries supplied additional information in certain services.
Question: When did Nielsen begin measuring television audiences?
Answer: Nielsen’s corporate history dates its national television measurement service to 1950. The Columbia Encyclopedia gives 1952 for the start of a television ratings service. The company added its local Nielsen Station Index in 1954.
Question: Did the 1963 FTC case establish wrongdoing by Arthur C. Nielsen Sr.?
Answer: No personal finding against Nielsen Sr. was established. The FTC complaint concerned the A. C. Nielsen Company’s competitive practices and ended in a corporate consent order in October 1963. The company agreed to the order without admitting the complaint’s substantive allegations. The separate congressional ratings hearings focused on questions about measurement methods and the industry.
Question: Are Nielsen and NielsenIQ the same company today?
Answer: No. The historical A. C. Nielsen Company worked in both consumer-goods research and audience measurement. The consumer intelligence operation became a separate company called NielsenIQ in 2021, while Nielsen continued in media measurement. Both trace their origins to Arthur C. Nielsen Sr.’s 1923 business.
