The Grammy Awards historically delayed its live ceremonies for West Coast viewers. In 2016, however, CBS began to allow its stations in the Western U.S. to carry the ceremony live as long as they also carried a prime time rebroadcast, before mandating all of its affiliates to air Grammys live all across the U.S. (inclusive of time zones outside the contiguous U.S.), with corresponding primetime rebroadcasts for viewers outside the Eastern and Central time zones. Despite shifting venues between Los Angeles and New York since 2018, the Grammys have continued to use the format, making it the first major award show to have consistently aired live every year across all U.S. time zones. Although the Primetime Emmy Awards, currently aired in rotation by ABC, CBS, Fox and NBC, began airing live coast-to-coast in the U.S. in 2010, the awards show followed suit with the Grammys in airing live simultaneously outside the contiguous U.S. time zones with CBS' telecast in 2017.
