Sporting events, including the Super Bowl, have been broadcast live in all U.S. time zones simultaneous with the primetime schedule of the Eastern time zone, for decades, resulting in announcements such as "4 Eastern, 1 Pacific" (generally shown as "4 ET/1 PT"). In the event of a sporting event leading into prime time on the East Coast, the following programs are often said to be "coming up next, except on the West Coast," as additional programming is shifted around to fill the time between the end of the event and the start of prime time on the West Coast. Many times, this is the programming that was preempted by the effectively earlier time slot in the western zones. 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).
