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...)

John Waters
"Homer's Phobia" is the fifteenth episode of The Simpsons' eighth season, which originally aired on the Fox network on February 16, 1997. It was the first episode written by Ron Hauge and was directed by Mike B. Anderson. John Waters (pictured) guest starred, providing the voice of the new character John. In the episode, Homer disassociates himself from new family friend John after discovering that John is gay. He worries that John will have a negative influence on his son, Bart. "Homer's Phobia" was the first episode to revolve entirely around homosexual themes, with the title being a pun on the word "homophobia". Originally, due to the controversial subject, the Fox censors found the episode unsuitable for broadcast, but this decision was reversed after a turnover in the Fox staff. It won four awards, including an Emmy for Outstanding Animated Program (For Programming One Hour or Less) and a GLAAD Media Award for "Outstanding TV - Individual Episode".

The Apollo TV camera refers to several television cameras used in the Apollo program's space missions, and on the later Skylab and Apollo-Soyuz Test Project missions, in the late 1960s and 1970s. These cameras varied in design, with image quality improving significantly with each successive model. Two companies made these various camera systems: RCA and Westinghouse. Originally, these slow-scan television (SSTV) cameras, running at 10 frames-per-second (fps), produced only black-and-white pictures and first flew on the Apollo 7 mission in October 1968. A color camera — using a field-sequential color system — flew on the Apollo 10 mission in May 1969, and every mission after that. The Color Camera ran at the North American standard 30 fps. The cameras all used image pickup tubes that were initially fragile, as one was irreparably damaged during the live broadcast of the Apollo 12 mission's first moonwalk. Starting with the Apollo 15 mission, a more robust, damage-resistant camera was used on the lunar surface. All of these cameras required signal processing back on Earth to make the frame rate and color encoding compatible with analog broadcast television standards.

Alistair Cooke
When television came roaring in after the war (World War II) they did a little school survey asking children which they preferred and why - television or radio. And there was this little 7-year-old boy who said he preferred radio 'because the pictures were better.'

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 for 19 years, 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 in 1981 was awarded the Presidential Medal of Freedom by President Jimmy Carter.

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.
