Television (TV) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission. Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than "radio broadcasting," which refers to an audio signal sent to radio receivers.
Television became available in crude experimental forms in the 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion. In the mid-1960s, color broadcasting was introduced in the U.S. and most other developed countries.
In 2013, 79% of the world's households owned a television set. The replacement of earlier cathode-ray tube (CRT) screen displays with compact, energy-efficient, flat-panel alternative technologies such as LCDs (both fluorescent-backlit and LED), OLED displays, and plasma displays was a hardware revolution that began with computer monitors in the late 1990s. Most television sets sold in the 2000s were still CRT, it was only in early 2010s that flat-screen TVs decisively overtook CRT. Major manufacturers announced the discontinuation of CRT, Digital Light Processing (DLP), plasma, and even fluorescent-backlit LCDs by the mid-2010s. LEDs are being gradually replaced by OLEDs. Also, major manufacturers have started increasingly producing smart TVs in the mid-2010s. Smart TVs with integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s.[better source needed] (Full article...)
In 1969, the children's television show Sesame Street premiered on the National Educational Television network (later succeeded by PBS) in the United States. Unlike earlier children's programming, the show's producers used research and over 1,000 studies and experiments to create the show and test its impact on its young viewers' learning. By the end of the program's first season, Children's Television Workshop (CTW), the organization founded to oversee Sesame Street production, had developed what came to be called "the CTW model": a system of planning, production, and evaluation that combined the expertise of researchers and early childhood educators with that of the program's writers, producers, and directors.
CTW conducted research in two ways: in-house formative research that informed and improved production, and independent summative evaluations conducted by the Educational Testing Service (ETS) during the show's first two seasons to measure the program's educational effectiveness. CTW researchers invented tools to measure young viewers' attention to the program. Based on these findings, the researchers compiled a body of data and the producers changed the show accordingly.
A satellite dish is a type of parabolic antenna designed with the specific purpose of transmitting signals to and/or receiving from satellites. A satellite dish is a particular type of microwave antenna. Satellite dishes come in varying sizes and designs, and are most commonly used to receive satellite television.
Daniel Irvin Rather Jr. (/ˈræðər/; born October 31, 1931) is an American journalist, commentator, and former national evening news anchor. He began his career in Texas, becoming a national name after his reporting saved thousands of lives during Hurricane Carla in September 1961. In his first national broadcast, he helped initiate the successful evacuation of 350,000 people. He reported on some of the most significant events of the modern age, such as the fall of the Berlin Wall, the Gulf War, 9/11, the Iraq War, and the war on terror.
Rather also famously reported from Dallas in November 1963 at the time that President John F. Kennedy had been assassinated. Based on such reporting, he was promoted at CBS News, where he served as White House correspondent beginning in 1964. He served as foreign correspondent in London and Vietnam over the next two years before returning to the White House correspondent position. He covered the presidency of Richard Nixon, including Nixon's trip to China, the Watergate scandal, and the president's resignation. (Full article...)
