Television, sometimes shortened to TV or telly, is a telecommunication medium used for transmitting moving images in monochrome (black and white), or in color, and in two or three dimensions and sound. The term can refer to a television set, a television show, 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 it would still be several years before the new technology would be marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and 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. The availability of various types of archival storage media such as Betamax and VHS tapes, high-capacity hard disk drives, DVDs, flash drives, high-definition Blu-ray Discs, and cloud digital video recorders has enabled viewers to watch pre-recorded material--such as movies--at home on their own time schedule. For many reasons, especially the convenience of remote retrieval, the storage of television and video programming now also occurs on the cloud (such as the video on demand service by Netflix). At the end of the first decade of the 2000s, digital television transmissions greatly increased in popularity. Another development was the move from standard-definition television (SDTV) (576i, with 576 interlaced lines of resolution and 480i) to high-definition television (HDTV), which provides a resolution that is substantially higher. HDTV may be transmitted in different formats: 1080p, 1080i and 720p. Since 2010, with the invention of smart television, Internet television has increased the availability of television programs and movies via the Internet through streaming video services such as Netflix, Amazon Video, iPlayer and Hulu.

Series creator Josh Schwartz during a 2007 Comic-Con event
"Premiere" is the series premiere of the television series The O.C., which first aired on the Fox network on August 5, 2003. Written by series creator Josh Schwartz (pictured) and directed by executive producer Doug Liman, the episode depicts the introduction of troubled teenager Ryan Atwood (Benjamin McKenzie) into the wealthy lifestyle of the Cohen family in Newport Beach, Orange County, California. The casting directors, Patrick J. Rush and Alyson Silverberg, began selecting the principal cast eight to ten weeks before filming started. Seth Cohen (Adam Brody) was based on Schwartz's experiences at the University of Southern California as a "neurotic Jewish kid from the East Coast in a land of water polo players". Other central characters in the episode are Seth's parents--Sandy (Peter Gallagher) and Kirsten (Kelly Rowan)--and teenage neighbor Marissa Cooper (Mischa Barton). The series premiere led the first half-hour of its time slot in viewership. It was generally well received by critics, and earned Schwartz a Writers Guild of America Award nomination for Best Screenplay in an Episodic Drama. Originally broadcast and released in a 1.33:1 aspect ratio, the episode was remastered in a widescreen ratio for the series DVD, released in November 2007.

1969. Stan Lebar, the project manager for Westinghouse's Apollo Television Cameras, shows the Field-Sequential Color Camera on the left, and the Monochrome Lunar Surface Camera on the right. The Color camera was used on all flights starting with Apollo 10, while the monochrome Lunar Surface Camera was used on Apollo 11, and captured Neil Armstrong's first steps on the Moon.

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.
