Live television refers to a television production broadcast in real-time, as events happen, in the present.
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, its initial high cost ($300 per one hour reel or $2,533 in 2014 dollars) meant it was only very gradually adopted. Some genres, such as soap operas, did not completely abandon live broadcasts until the mid-1970s.
Today, television networks provide most live television mostly for morning shows with television programs such as: Good Morning Britain, BBC Breakfast, This Morning, etc. broadcast live in the UK, and Today, Good Morning America & CBS This Morning in the US (airing live only in the Eastern Time Zone).
Spanish language morning shows (such as Despierta America & Un Nuevo Dia), unlike their English speaking counterparts, air live in the Eastern, Central, & Mountain time zones. (tape delayed in the Pacific time zone)
A few daytime talk shows in the USA broadcast live before a studio audience in select time zones. Shows such as LIVE! with Kelly & Michael & the Wendy Williams Show air live in the Eastern time zone only, while shows such as ABC's The View air live in the Eastern & Central time zones. The Talk on CBS airs live in the Eastern & Central time zones Monday through Thursday. (a separate program is taped on Thursday afternoon for airing on Friday) Affiliates in the remaining time zones air these programs on a tape delay.
Most other daytime talk shows (as well as late night programs) are taped before a live studio audience earlier in the day, and edited for later broadcast.
Talent shows (such as Dancing With The Stars & American Idol) air live in the Eastern & Central time zones, while ABC's Rising Star airs live in the Eastern, Central, & Mountain time zones. Other talent shows (such as The Voice & America's Got Talent) will tape programs featuring auditions and broadcast live performance shows in the Eastern & Central time zones where viewers have the opportunity to vote for their favorite contestants.
Most local television station newscasts are broadcast live in the U.S. as they are an essential medium for providing up-to-the-minute weather forecasts and breaking news stories. Broadcast television networks in the USA typically air their evening newscasts live in the Eastern & Central time zones.
When a major national breaking news event occurs, broadcast television networks will break into regularly scheduled programming and will televise a live "special report" in all time zones.
Cable news outlets (such as CNN & Fox News Channel) which broadcast 24 hours a day are live during the day, and air rebroadcasts of earlier shows during late night hours, except in cases where breaking news occurs.
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. Entertainment events such as sports television and The Academy Awards continue to be generally broadcast live.
Most award shows in the USA typically air live in the Eastern & Central time zones.
A more recent development by cable outlets (such as CNN & Fox News Channel) is to incorporate the word LIVE in their station logo (also known as a digital on-screen graphic) when those stations broadcast live content. Some (but not all) sports cable networks will opt to insert the word LIVE somewhere on the corner of the screen. Broadcast television networks typically do not display such a graphic during live programming. (although NBC did display the word LIVE next to their logo during its Olympic coverage when live content was being broadcast.)
Local television station newscasts display time and temperature during their broadcasts, and only display the word LIVE when they air a news report or a live shot on location.
Uses of live television
Live television is often used as a device, even when it is not necessary, in various types of programming to take advantage of these qualities, often to great success in terms of attracting viewers. The NBC live comedy/variety program Saturday Night Live, for example, has been on that network continuously since 1975 and airs live during the show's season which runs from September though May.
On September 25, 1997, NBC broadcast a special live episode of its hospital drama ER, which at the time ranked as the third most-watched episode of any medical drama program ever. Many television news programs, particularly local news ones in North America, have also used live television as a device to gain audience viewers by making their programs appear more exciting. With technologies such as production trucks, satellite truck uplinks, a news reporter can report live "on location" from anywhere where a story is happening in the city. This technique has attracted criticism for its overuse (like minor car accidents which often have no injuries) and resulting tendency to make stories appear more urgent than they actually are.
The unedited nature of live television can pose problems for television networks because of the potential for mishaps. To enforce the Federal Communications Commission (FCC) regulations, television networks often broadcast live programs on a slight broadcast delay to give them the ability to censor words and images while keeping the broadcast as "live" as possible.
Memorable events on live television

Live television episodes
Although all programs were once live, the use of video tape means that very few television programs in the modern era have ever attempted such a feat. In the U.S., soap operas including As the World Turns and The Edge of Night were broadcast live until 1975. The most recent scripted series to do so on a regular basis was the Charles S. Dutton series Roc in the 1992-93 season.
However, on rare occasions, a scripted series will do an episode live to attract ratings. In the U.S. and Canada, the episode is occasionally performed twice: once for the east coast which is composed of the Eastern Time Zone and Central Time Zone and again three hours later for the west coast which is composed of the Mountain Time Zone and the Pacific Time Zone. Notable examples of shows that have had a live episode include:
- Gimme a Break! (1985)
- Roc (The entire second season, 1993)
- ER (1997)
- Coronation Street (for its 40th anniversary in 2000 & its 50th anniversary in 2010)
- The Drew Carey Show (1999, 2000, & 2001)
- One Life to Live (Went live for an entire week of episodes in May 2002)
- The Bill (2003 & 2005)
- The Daily Show (2004, 2008, 2009)
- Blue Heelers (2004)
- Will & Grace (2005 & 2006)
- Air Farce Live (All episodes from October 2007 - December 2008)
- The West Wing (2005) - An episode ("The Debate") was presented as a live debate between presidential candidates
- Two Pints of Lager and a Packet of Crisps (2008)
- EastEnders (for its 25th anniversary in 2010)
- 30 Rock: season five, "Live Show" (2010) and season six, "Live from Studio 6H" (2012)
- WWE Raw
- WWE SmackDown (occasional live specials)
- Emmerdale (For its 40th Anniversary)
A live television advertisement was shown for the first time in 40 years to celebrate the arrival of the new Honda Accord in the United Kingdom. It was broadcast on Channel Four on 29 May 2008 at 20:10 during a special episode of 'Come Dine With Me'. The ad featured skydivers forming the letters of the word Honda over Spain.
Live television specials
Many live television specials were telecast during the pre-videotape era. Among the most successful were the 1955 and 1956 telecasts of Peter Pan, a 1954 musical adaptation of J. M. Barrie's 1904 play, starring Mary Martin, and Cyril Ritchard. This was such a hit that the show was restaged and rebroadcast (this time on videotape) with the same two stars and most of the rest of the cast in 1960, and rerun several times after that. The Peter Pan telecasts marked the first-ever telecasts of a complete Broadway musical with most of its original cast.
On December 5, 2013, NBC broadcast a live television special called "The Sound Of Music Live!" starring Carrie Underwood. This program aired live in the Eastern & Central time zones, and was the first television musical special to air live on NBC in almost fifty years.
