=== Hot kinescope ===

After the network of [[coaxial cable]] and [[Microwave radio relay|microwave relay]]s carrying programs to the [[West Coast of the United States|West Coast]] was completed in September 1951,<ref>"[https://web.archive.org/web/20081211102713/http://www.time.com/time/magazine/article/0,9171,889197,00.html Coast to Coast]", ''Time'', August 13, 1951.</ref> CBS and NBC instituted a ''hot kinescope'' process in 1952, where shows being performed in New York were transmitted west, filmed on two kinescope machines in [[35 mm camera|35&nbsp;mm]] negative and 16&nbsp;mm [[reversal film]] (the latter for backup protection) in Los Angeles, rushed to film processing, and then transmitted from Los Angeles three hours later for broadcast in the [[Pacific Time Zone]].<ref>Arthur Schneider, ''Jump Cut!: Memoirs of a Pioneer Television Editor'', McFarland, 1997, p. 23–32. {{ISBN|0-7864-0345-4}}. To save the time to make a print, the 35&nbsp;mm negative was broadcast, and electronically converted to a positive image. The soundtrack for the 35&nbsp;mm film was recorded on a separate 16&nbsp;mm filmstrip, and synchronized at playback. The soundtrack for the 16&nbsp;mm reversal film version was recorded on the same filmstrip as the image.</ref><ref>Albert Abramson, ''The History of Television, 1942 to 2000'', McFarland, 2003, p. 48. {{ISBN|0-7864-1220-8}}.</ref> In September 1956, NBC began making color ''hot kines'' of some of its color programs using a [[Kodacolor (motion picture)|lenticular film process]] which, unlike color negative film, could be processed rapidly using standard black-and-white methods.<ref>Showcase Productions, Inc.: ''[[Producers' Showcase]]'', [http://www.showcaseproductions.com/tech.htm Technical Considerations].</ref><ref>Abramson, ''The History of Television, 1942 to 2000'', p. 67.</ref> They were called ''hot kines'' because the film reels being delivered from the lab were still warm from the developing process.
