== Digital conversion ==
With the advent of [[digital television]], analog broadcasts were largely phased out. Most US NTSC broadcasters were required by the FCC to shut down their analog transmitters by February 17, 2009, however this was later moved to June 12, 2009. [[Low-power broadcasting|Low-power stations]], [[Class A television service|Class A stations]] and [[Broadcast relay station|translators]] were required to shut down by 2015, although an FCC extension allowed some of those stations operating on Channel 6 to operate until July 13, 2021.<ref>{{cite web |title=Media Bureau Reminds LPTV/TV Translators of Digital Transition Date (DA/FCC #: DA-20-724) |url=https://docs.fcc.gov/public/attachments/DA-20-724A1.pdf |access-date=January 17, 2021 |website=docs.fcc.gov |publisher=[[Federal Communications Commission]]}}</ref> The remaining Canadian analog TV transmitters, in markets not subject to the mandatory transition in 2011, were scheduled to be shut down by January 14, 2022, under a schedule published by [[Innovation, Science and Economic Development Canada]] in 2017; however the scheduled transition dates have already passed for several stations listed that continue to broadcast in analog (e.g. [[CFJC-TV]] Kamloops, which has not yet transitioned to digital, is listed as having been required to transition by November 20, 2020).<ref>{{cite web |date=April 2017 |title=Digital Television (DTV) Transition Schedule |url=https://www.ic.gc.ca/eic/site/smt-gst.nsf/vwapj/DTV-transition-schedule2017.pdf/$FILE/DTV-transition-schedule2017.pdf |access-date=July 22, 2021 |publisher=[[Innovation, Science and Economic Development Canada]]}}</ref>

Most countries using the NTSC standard, as well as those using other [[Analog television#Standards|analog television standards]], have switched to, or are in process of switching to, newer digital television standards, with there being at least four different standards in use around the world. North America, parts of [[Central America]], and [[South Korea]] are adopting or have adopted the [[ATSC standards|ATSC]] standards, while other countries, such as [[Japan]], are adopting or have adopted other standards instead of ATSC. After nearly 70&nbsp;years, the majority of over-the-air NTSC transmissions in the United States ceased on June 12, 2009,<ref name=":0">[http://www.fcc.gov/digital-television Digital Television].
