=== Digital television ===
[[Digital television]] (DTV) is the production and transmission of digital video from networks to consumers. This technique uses digital encoding instead of analog signals used prior to the 1950s.<ref>{{Cite book|last=Kruger|first=Lennard G.|url=https://www.worldcat.org/oclc/50684535|title=Digital television : an overview|date=2002|publisher=Novinka Books|others=Peter F.

Digital television's roots are tied to the availability of inexpensive, high-performance [[computers]]. It was not until the 1990s that digital TV became a real possibility.<ref name="benton">{{cite web |date=2008-12-23 |title=The Origins and Future Prospects of Digital Television |url=http://www.benton.org/initiatives/obligations/charting_the_digital_broadcasting_future/sec1 |publisher=[[Benton Foundation]]}}</ref> Digital television was previously not practically feasible due to the impractically high bandwidth requirements of [[uncompressed video]],<ref name="Barbero">{{cite journal |last1=Barbero |first1=M. |last2=Hofmann |first2=H. |last3=Wells |first3=N.
