Television, sometimes shortened to TV, is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set, or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports.

Television became available in crude experimental forms in the late 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, DLP, plasma, and even fluorescent-backlit LCDs by the mid-2010s. In the near future, LEDs are expected to be gradually replaced by OLEDs. Also, major manufacturers have announced that they will increasingly produce 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...)

Stephen Colbert
Stephen Colbert's performance at the 2006 White House Correspondents' Association Dinner mocked the Bush administration and the White House press corps, and subsequently generated significant controversy. Stephen Colbert was the featured entertainer for the 2006 White House Correspondents' Association Dinner, delivering a 20-minute speech and video presentation which was broadcast live on C-SPAN and MSNBC. Colbert spoke as the same character as the one he plays on The Colbert Report: an over-the-top send-up of a conservative pundit in the fashion of Bill O'Reilly and Sean Hannity. Colbert satirized the Bush administration and the White House press corps. Colbert spoke directly to President Bush several times, satirically praising his foreign policy, lifestyle, and beliefs, and referencing his low approval rating and popular reputation. Various reports give an impression that Bush did not take too kindly to the performance, as several of Bush's aides and supporters walked out during Colbert's speech, and one former aide said that the President had "that look that he's ready to blow." Reaction to the event caused it to become an Internet and media sensation, and ratings for The Colbert Report soared 37% in the week following the speech.

High-definition television (HDTV) is a digital television broadcasting system with greater resolution than traditional television systems (NTSC, SECAM, PAL). HDTV is digitally broadcast, because digital television (DTV) requires less bandwidth if sufficient video compression is used. HDTV technology was introduced in the United States in the 1990s by the Digital HDTV Grand Alliance, a group of television companies.

Selected biography - show another

Howard W. "Kroger" Babb (December 30, 1906 – January 28, 1980) was an American film producer and showman. His marketing techniques were similar to a travelling salesman's, with roots in the medicine show tradition. Self-described as "America's Fearless Young Showman", he is best known for his presentation of the 1945 exploitation film Mom and Dad, which was added to the National Film Registry of the Library of Congress in 2005.

Babb was involved in the production and marketing of many films and television shows, promoting each according to his favorite marketing motto: "You gotta tell 'em to sell 'em." His films ranged from sex education-style dramas to "documentaries" on foreign cultures, intended to titillate audiences rather than to educate them, maximizing profits via marketing gimmicks.
