Flat-screen television receivers on display for sale at a consumer electronics store in 2008

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...)

Lost's co-creator Damon Lindelof
Lost: Missing Pieces are thirteen video clips ranging in length from one to four minutes that aired during the hiatus between the third and fourth seasons of the television show Lost, from which the series is spun off. They generally became available to Verizon Wireless users on Mondays from November 2007 to January 2008 and were uploaded onto the American Broadcasting Company's website a week later for free streaming. The "mobisodes", which have also been referred to as "webisodes", are shot in Honolulu, Hawaii and produced by the same crew with the same cast as the television series; thus, all content is considered to be canon. The project was announced in November 2005 as the Lost Video Diaries; however, production was delayed several times due to contractual restrictions. Lost's writer-producers originally proposed the mobisodes as a self-contained story that would focus on two previously unseen characters of the Lost fictional universe. These characters would be played by actors who were not part of the Screen Actors Guild; however the entertainment guild refused to support such a project. After months of unsuccessful negotiating, the series was seemingly shelved by ABC. In June 2007, it was revealed that the mobisodes, which would be renamed Lost: Missing Pieces, would star the regular characters of Lost in thirteen short video clips unrelated to each other. Twelve scenes were newly shot; one was a deleted scene from the television series. Lost: Missing Pieces received minimal media attention and critical reviews were mixed.

A television station is a type of broadcast station that broadcasts both audio and video to television receivers in a particular area. Traditionally, TV stations made their broadcasts by sending specially-encoded radio signals over the air, called terrestrial television. Individual television stations are usually granted licenses by a government agency to use a particular section of the radio spectrum (a channel) through which they send their signals.

Cronkite in 1983

Walter Leland Cronkite Jr. (November 4, 1916 – July 17, 2009) was an American broadcast journalist who served as anchorman for the CBS Evening News from 1962 to 1981. During the 1960s and 1970s, he was often cited as "the most trusted man in America" after being so named in an opinion poll. Cronkite received numerous honors including two Peabody Awards, a George Polk Award, an Emmy Award, and the Presidential Medal of Freedom.

Cronkite reported many events from 1937 to 1981, including bombings in World War II; the Nuremberg trials; combat in the Vietnam War; the Dawson's Field hijackings; Watergate; the Iran Hostage Crisis; and the assassinations of President John F. Kennedy, civil rights pioneer Martin Luther King Jr., and Beatles musician John Lennon. He was also known for his extensive coverage of the U.S. space program, from Project Mercury to the Moon landings to the Space Shuttle. He was the only non-NASA recipient of an Ambassador of Exploration award. Cronkite is known for his departing catchphrase, "And that's the way it is", followed by the date of the broadcast.
