Network morning newscasts usually air at 7:00 a.m. (English-language network morning shows air live in the Eastern Time Zone and tape delayed for the remaining time zones, while the Spanish-language morning shows air live in the Eastern, Central, and Mountain time zones and are tape delayed in the Pacific Time Zone); network evening newscasts usually are broadcast live at 6:30 p.m. on the East Coast and broadcast live in both the Eastern and Central Time Zones, with a secondary live broadcast (otherwise known as a 'Western Edition") at 6:30 p.m. Pacific Time. "Today" was the first morning news program to be broadcast on American television and in the world, when it debuted on January 14, 1952; the earliest national evening news program was "The Walter Compton News", a short-lived 15-minute newscast that aired on the DuMont Television Network from 1947 to 1948.
