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...)

Michael Rosenbaum plays Lex Luthor
The pilot episode of the television series Smallville premiered on The WB on October 16, 2001. It was written by series creators Alfred Gough and Miles Millar, and directed by David Nutter. The episode introduces the characters of Clark Kent, an orphaned alien with superhuman abilities, and his friends and family who live in the fictional town of Smallville, Kansas. It follows Clark as he first learns of his alien origins, and attempts to stop a vengeful student from killing Smallville High School students. Using visual elements and dialogue, the episode introduces many themes that were designed to run either the course of the season or the entire series, such as the triangular relationships of the main characters. Filming for the pilot officially began four days after the last actor was cast for the series. When the series premiere aired, it broke several of The WB's viewership records. It was generally well received by critics, and was nominated for several awards, winning two.

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.

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 and then co-anchoring the CTV Television Network's national newscast. 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...)
