Live television

Live television is a television production broadcast in real-time, as events happen, in the present. Shows broadcast live include newscasts, morning shows, awards shows, sports programs, and, occasionally, episodes of television series. Live television was more common until the late 1950s, when videotape technology was invented. Because of the prohibitive cost, adoption was slow, and some television show remained live until the 1970s, such as soap operas. To prevent unforeseen issues, live television programs may be delayed, which allows censors to edit the program. Some programs may be broadcast live in certain time zones and delayed in others.

From the early days of television until about 1958, live television was used heavily, except for filmed shows such as I Love Lucy and Gunsmoke. Although videotape was invented in 1957, it cost $300 per one hour reel (equivalent to $2,558 in 2016) meaning it was only very gradually adopted. Some genres, such as soap operas, did not completely abandon live broadcasts until the mid-1970s.

In general, a live television program was more common for broadcasting content produced specifically for commercial television in the early years of the medium, before technologies such as video tape appeared. As video tape recorders (VTR) became more prevalent, many entertainment programs were recorded and edited before broadcasting rather than being shown live.

Television networks provide most live television for morning shows with television programs such as: Good Morning Britain, BBC Breakfast, This Morning, etc. broadcast live in the UK; Sunrise live in Australia; Canada AM live in Canada; and Today, Good Morning America, and CBS This Morning in the U.S., which air live only in the Eastern Time Zone. The only exceptions are CBS This Morning - Saturday and Sunday Today with Willie Geist, which air live in the Eastern and Central time zones. Spanish-language morning shows (such as Despierta America and Un Nuevo Día), unlike their English speaking counterparts, air live in the Eastern, Central, and Mountain time zones; they are tape delayed in the Pacific time zone.
