Arbitron is a consumer research company in the United States that collects listener data on radio audiences. It was founded as American Research Bureau (ARB) by Jim Seiler in 1949 and became national by merging with L.A. based Coffin, Cooper and Clay in the early 1950s. The company's initial business was the collection of broadcast television ratings.

The company changed its name to Arbitron in the mid 1960s, the namesake of the Arbitron System - a centralized statistical computer with leased lines to viewers' homes to monitor their activity. Deployed in New York, it gave instant ratings data on what people were watching. A reporting board would light up to indicate what home was listening to what broadcast.

Arbitron's syndicated radio ratings service collects data by selecting a random sample of a population throughout the U.S., primarily in 294 metropolitan areas, using a paper diary service two to four times a year and Portable People Meter (PPM) electronic audience measurement service 365 days a year.

The Sports Network, commonly abbreviated as TSN, is a Canadian English language Category C specialty channel and is Canada's leading English language sports TV channel. TSN premiered in 1984, in the first group of Canadian specialty cable channels. TSN is owned by CTV Specialty Television, a joint venture of Bell Media (80%) and ESPN (20%).

Bell Media also operates additional TSN-branded properties, including TSN2, TSN Radio 1050, TSN Radio 990, TSN Radio 1290 and two part-time regional feeds, Canadiens on TSN and Jets on TSN.

Licensed by the Canadian Radio-television and Telecommunications Commission (CRTC) on April 2, 1984 as Action Canada Sports Network, the channel was launched by the Labatt Brewing Company on September 1st of the same year as "The Sports Network", or "TSN". TSN was formed partly to promote Labatt's flagship products, but also to act as a vehicle for the Toronto Blue Jays baseball team (which was also owned by Labatt at the time). In 1989, TSN also launched a sister French language service, Réseau des sports (RDS).

George Horace Gallup (November 18, 1901 – July 26, 1984) was an American pioneer of survey sampling techniques and inventor of the Gallup poll, a successful statistical method of survey sampling for measuring public opinion.

Gallup was born in Jefferson, Iowa. He was a graduate of The Lawrenceville School and the University of Iowa, where he was a football player, a member of Sigma Alpha Epsilon fraternity, and editor of The Daily Iowan, an independent newspaper which serves the university campus. He earned his B.A. in 1923, his M.A. in 1925 and his Ph.D. in 1928.

In 1936, his new organization achieved national recognition by correctly predicting, from the replies of only 5,000 respondents, that Franklin Roosevelt would defeat Alf Landon in the U.S. Presidential election. This was in direct contradiction to the widely respected Literary Digest magazine whose poll based on over two million returned questionnaires predicted that Landon would be the winner. Not only did Gallup get the election right, he correctly predicted the results of the Literary Digest poll as well using a random sample smaller than theirs but chosen to match it.
