Editing Broadcast delay (section)

==Usage==
A short delay is often used to prevent [[profanity]], [[bloopers]], [[nudity]], or [[Obscenity|other undesirable material]] from making it to air. In this instance, it is often referred to as a "seven-second delay" or "profanity delay". Longer delays, however, may also be introduced, often to allow a show to air at the same time for the local market as is sometimes done with nationally broadcast programs in countries with multiple [[time zones]]. Considered as [[time shifting]], that is often achieved by a "tape delay", using a [[video tape recorder]], modern [[digital video recorders]], or other similar technology.

Tape delay may also refer to the process of broadcasting an event at a later scheduled time because a scheduling conflict prevents a live telecast, or a broadcaster seeks to maximize ratings by airing an event in a certain timeslot. That can also be done because of time constraints of certain portions, usually those that do not affect the outcome of the show, are edited out, or the availability of hosts or other key production staff only at certain times of the day, and it is generally applicable for [[cable television]] programs.

In countries that span multiple time zones and have influential domestic eastern regions, such as [[Television in Australia|Australia]], [[Effects of time zones on North American broadcasting|Canada, Mexico, and the United States]], television networks usually delay the entirety of their schedule for stations in the west, so [[prime time]] programming can be time shifted to air in local primetime hours to improve accessibility and viewership. Although Mexico and Canada have now regularly televised their live programs in real time simultaneously across all of their territories, in the U.S., "east" feeds usually target the [[Eastern Time Zone|Eastern]] and [[Central Time Zone|Central]] time zones, while "west" feeds are usually oriented towards the [[Pacific Time Zone|Pacific time zone]]. As a result, until today, many live programs, such as [[Music competition|music]] and [[Talent show|talent competition]] shows, are usually tape delayed for the [[West Coast of the United States|western]] half of the country and aired as-live (although they may include edits to streamline the broadcast or resolve technical faults). Australian network television schedule is largely patterned from the U.S. format.

In countries that span multiple time zones and are the most populous in their western or central regions, like [[Television in Brazil|Brazil]], [[Television in Russia|Russia]] and [[Television in Indonesia|Indonesia]], all television schedules nationwide are simultaneous with their broadcast sources, enabling full nationwide live telecasts regardless of time zones (although Russia conducts separate live primetime newscast versions for each range of time zones in that country). The continents of Europe and Africa, which both fall in the same range of time zones, are receptive to each other's live telecasts, while most of Asia from [[Television in India|India]] eastwards, which includes [[Television in China|China]] alongside the [[UTC+08:00|most populous time zone in the world]], also receive simultaneous live telecasts within those cluster of regions. 

International tape delays of live global events, intended by major television networks, dominated world television until the early 2010s. For example, during the [[Sydney Olympics]] in 2000 and the [[2008 Summer Olympics|Beijing Olympics]] in 2008, daytime events were occurring at early morning hours in the Americas, Africa, and Europe but were aired in the afternoon and evening hours live entirely in Asia, Australia, and Oceania. That made some broadcasters show high-profile events twice (live and then rebroadcast during prime time), but others withheld the same event to be broadcast solely during prime time. Often, tape-delaying of those events would mean editing them down for time considerations, highlighting what the broadcaster feels are the most interesting portions of the event, or advertising, resulting in reduced desired TV coverage for the given multiple sporting events.

However, since many live events became available via social media in the late 2000s, tape delays have become increasingly irrelevant because of [[live television]]'s resurgence as a broadcast format. Since the mid-2010s, several [[event television|high-profile entertainment]] programs with huge live global audiences like the [[Academy Awards]], [[Golden Globe Awards]], [[Grammy Awards]], [[Emmy Awards]] and [[Tony Awards]], yearly specials like the [[Miss Universe]] and [[Miss World]] pageants, and major sporting events like the [[Olympic Games]], [[FIFA World Cup]] and the [[National Football League]]'s [[Super Bowl]], air to totality live on both television and the internet virtually all across the world's time zones in and out of their countries of origin. In addition, television networks nowadays mandate prime time rebroadcasts (featuring edits as desired by broadcasters) for regions that are not covered by the original live primetime broadcasting and previously and solely relied on delayed telecasts on prime time among these otherwise live events.

In certain professional competitions, like chess, broadcast delays may be used to prevent cheating or other irregularities.<ref>{{cite web |url=https://en.chessbase.com/post/revisited-15-minute-broadcast-delay |title=Revisited: 15-minute broadcast delay |date=14 September 2022 |access-date=2022-10-15}}</ref>
