The first two systems of a television were the mechanical television and the electronic television. The mechanical system was developed out of Nipkow’s disk that was pioneered by John Logie Baird, he gave a first world public demonstration of his television in London, 1926. There are rotating disks to scan moving images into pulses that are transmitted to the screen, this television was a low resolution with lights and dark. There were only about 240 lines of resolutions which means it was always fuzzy, there was a limited number of new pictures that could seen per second. A year later, the British Broadcasting Corporation accepted this system, by 1932 there was 10,000 sets that were sold. The electronic television could scan a picture in horizontal lines which was producing the image close to immediately. This television started to replace the mechanical television because there was a better picture quality, no noise, and fewer limitations. By the 1939, the mechanicals television was replaced with the electronic television.
By the 1950’s, the technology was evolving into producing color televisions by John Logie Baird. He used his black and white television system but started to use three spirals of each primary color. This year was the golden age of televisions, before the golden age less than 10,000 tv sets were in the united states. Once the golden age hit it went up around 6 million and by 1960 more than 60 tv sets had been sold. In 1984, the Cable Act came to life, it was for industries to expand, nearly 53 million households were subscribed to a cable television. In the 2000’s the analog system took over the color televisions, nearly half of the Americans had high-definition television which provided perfect clear screens.
In the 1950’s television would not broadcast current events or political issues, but March of 1952 Edward R. Murrow broadcasted a show called See It Now which showed the potential communist infiltration in the U.S. institutions. After that, entertainment programs also tackled these controversial issues. In the 1960’s news started to enlighten people on realities of real-world events in vivid detail. For example, On November 22,1963 people learned about the assassination of John F. Kennedy. Not so long after that the nations first televised war took place, they showed horrific images such as children being burned, being tortured of the Vietnam war. This started the antiwar for Americans.
In 1969, Public broadcasting service was established to report by the Carnegie commission on educational television. The report concluded that the government finance public television to provide diversity of programming during the network era (years of 1950 to 1970). During this time, there was the big three which is three major networks that we named ABC,CBS,and NBC that controlled the television industry, the big three accounted for more than 95% of prime time. Until Rupert Murdoch came along, in the 1986, Murdoch lunched the Fox network to challenge the big three. Fox became an addition to the big three, during the 1994, 43% United states households watched the big four, but by the time 2009 hit it went down to 27%.
The film called “Tuning in to Media: Literacy for the information Age Part Two” talks about the power of representations to shape our expectations of beliefs and attitudes media that provides us with information about the world. The shows that they show are sophisticated enough to take the point of view of the black person who says “look all the businesses around elsewhere and I got what I could get while I got” and that’s not a decent logic for what he did. The focus is between the blacks and Koreans than looking at the class issue of the rich versus the poor. For me, media will portray any angle they can no matter what the cause even though it is affecting our people.
