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...)

Actor Matthew Fox stars as Dr. Jack Shephard in ABC's Lost
"Through the Looking Glass" is the twenty-second episode and season finale of the third season – sixty-ninth episode overall – of the ABC television series Lost. It was written by co-creator/executive producer Damon Lindelof and executive producer Carlton Cuse, and directed by executive producer Jack Bender. When the episode first aired on May 23, 2007 in the United States and Canada, it was watched by an average of 14 million American viewers. Like the previous two season finales, it was two hours long with advertisements, which is twice the length of a normal episode. It was split when released on DVD. The season finale was critically acclaimed and the episode has garnered a number of awards and nominations. The episode begins on December 22, 2004, ninety-two days after the crash of Oceanic Airlines Flight 815. The battle between the crash survivors and the dangerous and mysterious island inhabitants referred to as the "Others" comes to a head as ten of the Others ambush the survivors' camp and are subsequently killed. Meanwhile, Jack Shephard (played by Matthew Fox) leads most of the survivors to the island's radio tower to communicate with a nearby ship. This is the first Lost episode to feature flashforwards, as opposed to the customary flashbacks. Actor Dominic Monaghan makes his final appearance with main cast credit as Charlie Pace in this episode.

Selected biography - show another

Rudolph Cartier (born Rudolph Kacser, renamed himself in Germany to Rudolph Katscher; 17 April 1904 – 7 June 1994) was an Austrian television director, filmmaker, screenwriter and producer who worked predominantly in British television, exclusively for the BBC. He is best known for his 1950s collaborations with screenwriter Nigel Kneale, most notably the Quatermass serials and their 1954 adaptation of George Orwell's dystopian novel Nineteen Eighty-Four.

After studying architecture and then drama, Cartier began his career as a screenwriter and then film director in Berlin, working for UFA Studios. After a brief spell in the United States he moved to the United Kingdom in 1935. Initially failing to gain a foothold in the British film industry, he did some scripting work for BBC Television in 1939 before the service was suspended at the outbreak of the Second World War. After the war, he occasionally worked for British films before he was again hired by the BBC in 1952. He soon became one of the public service broadcaster's leading directors and went on to produce and direct over 120 productions in the next 24 years, ending his television career with the play Loyalties in 1976.
