Television became accessible to the population by the price and the amount of entertainment it provided for everyone in that household from the growing variety of tv show options.
Some of the first experiments with televisions began 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. A mechanical television system which scanned images using a rotating disk with holes arranged in a spiral pattern had been demonstrated in the 1920s. However, that invention scanned images with a beam of electrons
RCA televised the opening of the New York World's Fair with a speech by President Franklin Delano Roosevelt, who was the first president to be on television. Later in the 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 game between 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.
The film industry faced an investigation because political beliefs suddenly became grounds for getting fired. Most of the producers, writers, and actors who were accused of having had left-wing leanings found themselves blacklisted, unable to get work. CBS even instituted a loyalty oath for its employees. Among the few individuals in television well positioned enough and brave enough to take a stand against McCarthyism was the distinguished former radio reporter Edward R. Murrow. McCarthyism is a campaign against alleged communists in the US government and other institutions carried out under Senator Joseph McCarthy in the period 1950–1954. Many of the accused were blacklisted or lost their jobs even though most did not in fact belong to the Communist Party.
The golden age of television is Between 1953 and 1955. The golden age is when television programming began to take some steps away from radio formats an example of which was Peter Pan (1955), starring Mary Martin, which attracted 60 million viewers. New types of shows were made to satisfy the entertainment cravings of everyone with a tv.
The election of a president in 1960, John F. Kennedy, seemed to provide evidence of how profoundly television would change politics. Commentators pointed to the first televised debate that fall between Kennedy, the Democratic candidate for president, and Vice-President Richard M. In the beginning they had ranks that nixon was in the lead but when the tv started broadcasting this they saw nixon's lack of hygiene and attention to detail which made JFK win in the end. I think TV has changed the ways politics work because it gives the viewers a better understanding of what they are actually gonna be voting for in the end.
The three major networks have always been in a continual race for ratings and advertising dollars. CBS and NBC dominated through the mid-1970s, when ABC, traditionally regarded as a poor third, rose to the top of the ratings, largely because of shrewd scheduling.
A Carnegie Commission report in 1967 recommended the creation of a fourth, noncommercial, public television network built around the educational nonprofit stations already in operation throughout the United States to see television and noncommercial. I think it was necessary because it’s good to have that balance of what's good to watch and not. I also think that it's necessary for today because of all the growing controversy of everyones opinions and the new ones that are coming along.
Some examples of cable networks are like a shopping channel or a movie channel. They are different from other networks because that channel only focuses on one main thing. Some powerful cable networks today are the sports network and the food network because they gain a lot of interest from the public eye.
