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 flat-panel, mainly LEDs. 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. (Full article...)

Big Bird's star on the Hollywood Walk of Fame
The history of Sesame Street began with its conception in 1966 during discussions between television producer Joan Ganz Cooney and Carnegie Corporation vice president Lloyd Morrisett. Their goal was to create a children's television show that would "master the addictive qualities of television and do something good with them", such as helping young children prepare for school. After two years of research, the newly formed Children's Television Workshop (CTW) received a combined grant of $8 million from the Carnegie Corporation, the Ford Foundation, and the U.S. federal government to create and produce a new children's television show. Sesame Street premiered on November 10, 1969. Featuring animation, live shorts, humor, celebrity appearances, and Jim Henson's Muppets such as Big Bird (star pictured), it was the first television program of its kind to base its contents and production values on laboratory and formative research, and the first to include a curriculum "detailed or stated in terms of measurable outcomes". Initial responses to the show included adulatory reviews, some controversy, and high ratings. By its 40th anniversary in 2009, Sesame Street was broadcast in over 120 countries, and 20 independent international versions had been produced.

Jennings in 2002

Peter Charles Archibald Ewart Jennings CM (July 29, 1938 – August 7, 2005) was a Canadian-American television journalist, best known for serving as the sole anchor of ABC World News Tonight from 1983 until his death from lung cancer in 2005. Despite dropping out of high school, Jennings transformed himself into one of American television's most prominent journalists.

Jennings started his career early, hosting a Canadian radio show at age 9. He began his professional career with CJOH-TV in Ottawa during its early years, anchoring the local newscasts and hosting the teen dance show Saturday Date on Saturdays. In 1965, ABC News tapped him to anchor its flagship evening news program. Critics and others in the television news business attacked his inexperience, making his job difficult. He became a foreign correspondent in 1968, reporting from the Middle East. (Full article...)
