The Invention of Television

Few inventions have had as much effect on contemporary American society as television. Before 1947 the number of U.S. homes with television sets could be measured in the thousands. By the late 1990s, 98 percent of U.S. homes had at least one television set, and those sets were on for an average of more than seven hours a day. The typical American spends (depending on the survey and the time of year) from two-and-a-half to almost five hours a day watching television. It is significant not only that this time is being spent with television but that it is not being spent engaging in other activities, such as reading or going out or socializing.

EXPERIMENTS

Electronic television was first successfully demonstrated in San Francisco on Sept. 7, 1927. The system was designed by Philo Taylor Farnsworth, a 21-year-old inventor who had lived in a house without electricity until he was 14. While still in high school, Farnsworth had begun to conceive of a system that could capture moving images in a form that could be coded onto radio waves and then transformed back into a picture on a screen. Boris Rosing in Russia had conducted some crude experiments in transmitting images 16 years before Farnsworth's first success. Also, a mechanical television system, which scanned images using a rotating disk with holes arranged in a spiral pattern, had been demonstrated by John Logie Baird in England and Charles Francis Jenkins in the United States earlier in the 1920s. However, Farnsworth's invention, which scanned images with a beam of electrons, is the direct ancestor of modern television. The first image he transmitted on it was a simple line. Soon he aimed his primitive camera at a dollar sign because an investor had asked, "When are we going to see some dollars in this thing, Farnsworth?"

EARLY DEVELOPMENT

RCA, the company that dominated the radio business in the United States with its two NBC networks, invested $50 million in the development of electronic television. To direct the effort, the company's president, David Sarnoff, hired the Russian-born scientist Vladimir Kosma Zworykin, who had participated in Rosing's experiments. In 1939, RCA televised the opening of the New York World's Fair, including a speech by President Franklin Delano Roosevelt, who was the first president to appear on television. Later that year RCA paid for a license to use Farnsworth's television patents. RCA began selling television sets with 5 by 12 in (12.7 by 25.4 cm) picture tubes. The company also began broadcasting regular programs, including scenes captured by a mobile unit and, on May 17, 1939, the first televised baseball gameÑbetween Princeton and Columbia universities. By 1941 the Columbia Broadcasting System (CBS), RCA's main competition in radio, was broadcasting two 15-minute newscasts a day to a tiny audience on its New York television station.

Early television was quite primitive. All the action at that first televised baseball game had to be captured by a single camera, and the limitations of early cameras forced actors in dramas to work under impossibly hot lights, wearing black lipstick and green makeup (the cameras had trouble with the color white). The early newscasts on CBS were "chalk talks," with a newsman moving a pointer across a map of Europe, then consumed by war. The poor quality of the picture made it difficult to make out the newsman, let alone the map. World War II slowed the development of television, as companies like RCA turned their attention to military production. Television's progress was further slowed by a struggle over wavelength allocations with the new FM radio and a battle over government regulation. The Federal Communications Commission's (FCC) 1941 ruling that the National Broadcasting Company (NBC) had to sell one of its two radio networks was upheld by the Supreme Court in 1943. The second network became the new American Broadcasting Company (ABC), which would enter television early in the next decade. Six experimental television stations remained on the air during the warÑone each in Chicago, Philadelphia, Los Angeles, and Schenectady, N.Y., and two in New York City. But full-scale commercial television broadcasting did not begin in the United States until 1947.

THE BEGINNING OF COMMERCIAL TELEVISION

By 1949 Americans who lived within range of the growing number of television stations in the country could watch, for example, The Texaco Star Theater (1948), starring Milton Berle, or the children's program, Howdy Doody (1947Ð60). They could also choose between two 15-minute newscastsÑCBS TV News (1948) with Douglas Edwards and NBC's Camel News Caravan (1948) with John Cameron Swayze (who was required by the tobacco company sponsor to have a burning cigarette always visible when he was on camera). Many early programsÑsuch as Amos 'n' Andy (1951) or The Jack Benny Show (1950Ð65)Ñwere borrowed from early television's older, more established Big Brother: network radio. Most of the formats of the new programsÑnewscasts, situation comedies, variety shows, and dramasÑwere borrowed from radio, too (see radio broadcasting and television programming). NBC and CBS took the funds needed to establish this new medium from their radio profits. However, television networks soon would be making substantial profits of their own, and network radio would all but disappear, except as a carrier of hourly newscasts. Ideas on what to do with the element television added to radio, the visuals, sometimes seemed in short supply. On news programs, in particular, the temptation was to fill the screen with "talking heads," newscasters simply reading the news, as they might have for radio. For shots of news events, the networks relied initially on the newsreel companies, whose work had been shown previously in movie studios. The number of television sets in use rose from 6,000 in 1946 to some 12 million by 1951. No new invention entered American homes faster than black and white television sets; by 1955 half of all U.S. homes had one.

McCARTHYISM

In 1947 the House Committee on Un-American Activities began an investigation of the film industry, and Sen. Joseph R. McCarthy soon began to inveigh against what he claimed was Communist infiltration of the government. Broadcasting, too, felt the impact of this growing national witch-hunt. Three former members of the Federal Bureau of Investigation (FBI) published "Counterattack: The Newsletter of Facts on Communism," and in 1950 a pamphlet, "Red Channels," listed the supposedly Communist associations of 151 performing artists. Anti-Communist vigilantes applied pressure to advertisersÑthe source of network profits. Political beliefs suddenly became grounds for getting fired. Most of the producers, writers,
