Television is an integral part of our daily entertainment. for which of these processes has the television not used any form of energy?

Learning Objectives • Identify four roles the media performs in our society. • Recognize events that affected the adoption of mass media. • Explain how different technological transitions have shaped media industries. In 2010, Americans could turn on their television and find 24-hour news channels as well as music videos, nature documentaries, and reality shows about everything from hoarders to fashion models. That’s not to mention movies available on demand from cable providers or television and video available online for streaming or downloading. Half of U.S. households receive a daily newspaper, and the average person holds 1.9 magazine subscriptions (State of the Media, 2004) (Bilton, 2007). A University of California, San Diego study claimed that U.S. households consumed a total of approximately 3.6 zettabytes of information in 2008—the digital equivalent of a 7-foot high stack of books covering the entire United States—a 350 percent increase since 1980 (Ramsey, 2009). Americans are exposed to media in taxicabs and buses, in classrooms and doctors’ offices, on highways, and in airplanes. We can begin to orient ourselves in the information cloud through parsing what roles the media fills in society, examining its history in society, and looking at the way technological innovations have helped bring us to where we are today. What Does Media Do for Us? Media fulfills several basic roles in our society. One obvious role is entertainment. Media can act as a springboard for...

The week in May when ABC, CBS, NBC and Fox traditionally unveiled programming plans in glitzy presentations to advertisers has always spoken to the networks' power over popular culture Television in the United States, the body of Overview Although television was first regarded by many as “ One aspect of early television that can never be recaptured is the The 1950s was a time of remarkable achievement in television, but this was not the case for the entire medium. American viewers old enough to remember TV in the ’50s may fondly recall the shows of programs were the exception; most of television during its formative years could be aptly described, as it was by one Broadway playwright, as “amateurs playing at home movies.” The underlying problem was not a shortage of talented writers, producers, and performers; there were plenty, but they were already busily involved on the Pop Culture Quiz Fortunately, the dearth of talent was short-lived. Although it would take at least another decade before areas such as news and sports coverage approached their potential, more than enough excellence in the categories of The Golden Age: 1948–59 Getting started Until the fall of 1948, regularly scheduled programming on the four networks—the pm, Eastern Standard Time). Sales of television sets were low, so, even if programs had been available, their potential audience was limited. To encourage sales, daytime sports broadcasts were scheduled on weekends in an effort to lure heads of househo...

Learning Objectives • Identify two technological developments that paved the way for the evolution of television. • Explain why electronic television prevailed over mechanical television. • Identify three important developments in the history of television since 1960. Since replacing radio as the most popular mass medium in the 1950s, television has played such an integral role in modern life that, for some, it is difficult to imagine being without it. Both reflecting and shaping cultural values, television has at times been criticized for its alleged negative influences on children and young people and at other times lauded for its ability to create a common experience for all its viewers. Major world events such as the John F. Kennedy and Martin Luther King assassinations and the Vietnam War in the 1960s, the Challenger shuttle explosion in 1986, the 2001 terrorist attacks on the World Trade Center, and the impact and aftermath of Hurricane Katrina in 2005 have all played out on television, uniting millions of people in shared tragedy and hope. Today, as Internet technology and satellite broadcasting change the way people watch television, the medium continues to evolve, solidifying its position as one of the most important inventions of the 20th century. The Origins of Television Inventors conceived the idea of television long before the technology to create it appeared. Early pioneers speculated that if audio waves could be separated from the electromagnetic spectrum t...

Transmission and reception involve the components of a television system that generate, transmit, and utilize the television signal wave form (as shown in the block diagram). The scene to be televised is focused by a lens on an image sensor located within the camera. This produces the picture signal, and the synchronization and blanking pulses are then added, establishing the complete composite video wave form. The composite video signal and the sound signal are then imposed on a Generating the colour picture signal As is pointed out in the section Immediately following the colour camera is the colour coder, which converts the primary-colour signals into the luminance and chrominance signals. The luminance signal is formed simply by applying the primary-colour signals to an electronic addition circuit, or adder, that adds the I (orange-cyan) and Q (magenta-yellow) signals. These are applied simultaneously to a The chrominance subcarrier in NTSC systems is generated in a precise electronic oscillator at the standard value of 3.579545 megahertz. Samples of this subcarrier are injected into the signal wave form during the blank period between line scans, just after the horizontal synchronizing pulses. These samples, collectively referred to as the “colour burst,” are employed in the receiver to control the synchronous detector, as mentioned in the section The carrier signal The picture signal generated as described above can be conveyed over short distances by wire or cable i...

Learning Objectives • Identify ways in which American culture is reflected on television. • Identify ways in which television affects the development of American culture. Since its inception as an integral part of American life in the 1950s, television has both reflected and nurtured cultural mores and values. From the escapist dramas of the 1960s, which consciously avoided controversial issues and glossed over life’s harsher realities in favor of an idealized portrayal, to the copious reality TV shows in recent years, on which participants discuss even the most personal and taboo issues, television has held up a mirror to society. But the relationship between social attitudes and television is reciprocal; broadcasters have often demonstrated their power to influence viewers, either consciously through slanted political commentary, or subtly, by portraying controversial relationships (such as single parenthood, same-sex marriages, or interracial couplings) as socially acceptable. The symbiotic nature of television and culture is exemplified in every broadcast, from family sitcoms to serious news reports. Cultural Influences on Television In the 1950s, most television entertainment programs ignored current events and political issues. Instead, the three major networks (ABC, NBC, and CBS) developed prime-time shows that would appeal to a general family audience. Chief among these types of shows was the Leave It to Beaver, The Donna Reed Show, and The Adventures of Ozzie and ...
