Introduction

Television (TV) is a telecommunication medium used for transmitting moving images in monochrome (black and white), or in colour, and in two or three dimensions and sound. The term can refer to a television set, a television program ("TV show"), or the medium of television transmission. Television is a mass medium for advertising, entertainment and news.

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 TV broadcasting became popular in the United States and Britain, 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 US and most other developed countries. The availability of multiple types of archival storage media such as Betamax, VHS tape, local disks, DVDs, flash drives, high-definition Blu-ray Discs, and cloud digital video recorders have 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 occurs on the cloud. 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 various 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, Hulu, Roku and Chromecast.

The Simpsons Movie is a 2007 American animated comedy film based on the animated television series The Simpsons. The film was directed by David Silverman, produced by James L. Brooks, Matt Groening, Al Jean, Mike Scully, and Richard Sakai, and written by Scully, Jean, Brooks, Groening, George Meyer, David Mirkin, Mike Reiss, John Swartzwelder, Jon Vitti, Ian Maxtone-Graham, and Matt Selman. It stars the regular television cast of Dan Castellaneta, Julie Kavner, Nancy Cartwright, Yeardley Smith, Hank Azaria, Harry Shearer, Tress MacNeille and Pamela Hayden and features Albert Brooks in a prominent guest role, as well as Tom Hanks and Green Day in smaller ones. After previous attempts to create a film version of The Simpsons had failed because of script length and lack of staff, production began in 2001. The script was re-written one hundred times continuing after animation had begun. This meant that "two films' worth" of finished material was cut, including cameos from Isla Fisher, Minnie Driver, Erin Brockovich, and Kelsey Grammer. The film premiered in Springfield, Vermont, which won the right to hold it through a Fox competition. The film was a box office success, and received positive reception from film critics, though some felt the film was too short.

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.
