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. All four major English networks and the two largest Spanish networks also carry political talk programs on Sunday mornings (NBC's Meet the Press, ABC's This Week, CBS' Face the Nation, Fox's sole news program Fox News Sunday, Univision's Al Punto, and Telemundo's Enfoque); of these programs, Meet the Press holds the distinction of being the longest-running American television program as it has aired since November 6, 1947. The U.S. is one of the few countries in which broadcast networks provide overnight or early morning national news programs, in addition to those airing in the morning and early evening. CBS and ABC are currently the only networks that produce overnight news programs on weeknights in the form of Up to the Minute and World News Now, respectively; NBC previously produced overnight newscasts at different times, both of which have since been cancelled: NBC News Overnight from 1982 to 1983, and NBC Nightside from 1991 to 1998 (NBC currently does not offer a late night newscast, although the network currently airs rebroadcasts of the fourth hour of Today, and sister network CNBC's Mad Money on weeknights). Spanish-language news programs are provided by Univision, which produces early and late evening editions of its flagship evening news program Noticiero Univision seven nights a week (and was the only nightly newscast on the major Spanish networks until Telemundo resumed its weekend newscasts in October 2014), along with weekday afternoon newsmagazine Primer Impacto and weekday morning program Despierta America; Telemundo, which has a daily flagship evening newscast Noticias Telemundo, along with weekday morning program Hoy Día (which replaced Un Nuevo Día in 2021) and weekday afternoon newsmagazine Al Rojo Vivo; Estrella TV, which produces the weekday-only flagship news program Noticiero Estrella TV and the primetime newscast Cierre de Edición; and
