MediaWorks launched an hour-delayed timeshift channel of the TV3 feed with Auckland regional advertising on 30 March 2009.
On 1 July 2019, MediaWorks launched an hour-delayed timeshift version of ThreeLife, replacing The Edge TV which went online only.
The Nick Jr. Channel notably only maintained a single Eastern Time feed until 2013, which led to controversy when the channel launched its adult-oriented NickMom programming block, which had started at 7:00 p.m. in the Pacific Time Zone and earlier in Alaska and Hawaii, at times when preschoolers would still be awake in those regions; Nick Jr. would later launch a West Coast feed due to complaints from some parents about the content featured on the NickMom block.
Live nationwide U.S. airings of international sporting events like the FIFA World Cup on Fox and the Olympic Games on NBC, beginning in the late 2010s, are simultaneous with the actual live global broadcast regardless of the hosting nation, resulting in adjustments by networks as most of their games may fall outside the primetime slots of any of the U.S. time zones at the time of the event (and, on occasion, televise live during daytime with primetime encores when the hosting nation is located outside the Americas).
Until the mid-2000s, several awards shows were routinely tape-delayed for viewers on the West Coast while being transmitted live east of the Rockies.
However, by the late 2000s, with the rise of social media like Twitter and Facebook around discussion of television programming, many of them now choose to air their ceremonies live all across the mainland U.S., especially those held in the Los Angeles area where tape-delayed broadcasts had been conducted by the networks in the past.
The transition was ushered in 2009 by NBC with the Golden Globe Awards, primarily aiming to prevent spoilers for western viewers previously relying on telecasts delayed until local prime time.
The Primetime Emmy Awards, on rotation among ABC, CBS, Fox, and NBC, joined the Grammys in airing completely live all across the U.S., including Hawaii, starting with CBS' telecast turn in 2017 to resolve the complaints of tape-delaying live American TV shows outside the mainland continent.
Meanwhile, the MTV Video Music Awards have regularly aired live all across U.S. territories simultaneously with The CW as part of its post-COVID-19 pandemic adjustments since 2020.
In particular, network-timeshifting of live U.S. television broadcasts has since steadily declined amidst the rise of social media and online streaming services, simultaneous with the increasing trend of U.S. entertainment shows towards live coast-to-coast American broadcasting that earned renewed importance for they are "DVR-proof" in terms of ratings and social purposes.
Now more rarely, lesser ceremonies continue to air live in the Eastern and Central time zones while tape-delayed for all other U.S. territories, as their airtime is often purchased as a brokered programming arrangement, and as disruption for those ceremonies (often on weekdays) is much less tolerated by their airing network's affiliate base west of the Rockies.
Other ceremonies that do not air live are taped in advance, including those broadcast on weekend nights in the U.S., to allow standards and practices to watch the ceremony in advance and determine cuts for profanity or content to insert a bleep censor or cut-away, and the producers can make cuts for time and superfluous items such as longer walks than expected by an award winner to the stage or a rare botched performance with the replacement of dress rehearsal footage.
In practice, only the CBC delays its entire prime time schedule for each time zone; the commercial networks typically schedule programs to maximize their ability to claim simultaneous substitution rights (which allows local broadcast stations to require U.S. broadcast stations' signals on television providers to be overridden with their own, if they are airing the exact same program in simulcast), resulting in programs often being scheduled in pattern with an airing from the Eastern or Pacific zones.
In Latin America, Spanish-language pay television programming used to be broadcast without delay in Argentina and Uruguay, and delayed in most countries; this situation was common in networks that broadcast one video feed for distribution to the rest of Latin American countries, as it centred their schedule using the Argentine time zone (HBO, Moviecity).
However, this stopped being the case on basic-tier subscription TV with the launch of different regional feeds centred on local time zones, either based on Mexico, Colombia, Peru or Chile.
