The history of live TV is, for most of its first decades, simply the history of television. Before recording technology caught up, nearly everything on screen went out live. This short history follows live television from the first experiments in the 1920s to the streaming services that now carry it to phones and smart TVs around the world.
Early experiments: the 1920s
The idea of sending pictures by wire or radio is older than the technology to do it. In 1884 the German engineer Paul Nipkow patented a spinning disk that could scan an image line by line, and that principle shaped the first working systems.
On 26 January 1926, the Scottish inventor John Logie Baird gave the first public demonstration of television images in motion, at his laboratory on Frith Street in London. His mechanical system produced a small, coarse picture, but it showed that live moving images could be transmitted. In the United States, Philo Farnsworth demonstrated an all-electronic system in 1927, and electronic cameras and picture tubes, developed by Farnsworth, Vladimir Zworykin and others, soon replaced mechanical scanning.
The first regular broadcasts: 1930s
Germany started a regular television service in Berlin in March 1935, broadcasting a few times a week, and it showed live coverage of the 1936 Berlin Olympics to public viewing rooms. In Britain, the BBC Television Service launched from Alexandra Palace in London on 2 November 1936, and it is often described as the world’s first regular high-definition television service.
In the United States, NBC televised President Franklin D. Roosevelt opening the New York World’s Fair on 30 April 1939, and commercial television was authorised in 1941. The Second World War then slowed growth almost everywhere. The BBC service was suspended in September 1939 and did not return until June 1946.
The golden age of live television: 1940s and 1950s
After the war, television sets spread quickly through North American and European homes. Dramas, comedy shows, variety programmes and news were performed and transmitted live, often from small studios. Mistakes went straight to air, which is part of why that era is remembered so vividly.
Two milestones from this period stand out. On 4 September 1951, President Harry Truman’s speech at the Japanese peace treaty conference in San Francisco became the first live coast-to-coast television broadcast in the US. On 2 June 1953, the coronation of Queen Elizabeth II was broadcast live, and for many families in Britain it was the first time they watched television at all.
In 1956, the American company Ampex introduced a practical videotape recorder. Programmes could now be recorded, edited and shown later at a different time, so live broadcasting gradually became a choice reserved for news, sport and special events rather than the default.
Satellites take live TV global: 1960s and 1970s
The Telstar 1 communications satellite was launched on 10 July 1962, and on 23 July 1962 it carried the first publicly available live television pictures across the Atlantic. Satellites soon made it possible to share live pictures between continents. In 1967, the programme Our World linked broadcasters in many countries for the first live global television production, and on 20 July 1969 hundreds of millions of people around the world watched live pictures of the Apollo 11 Moon landing.
In the 1970s, cable operators began receiving channels by satellite, which made national cable networks practical and greatly increased the number of channels available in many homes.
Cable and 24-hour news: 1980s and 1990s
CNN launched on 1 June 1980 as the first 24-hour television news channel in the US. Rolling news changed what “live” meant: instead of scheduled bulletins, viewers could switch on at any hour and see events as they unfolded. Other countries and regions followed with their own 24-hour news channels, and live coverage of wars, elections and disasters became a central part of how people followed world events.
The digital switchover: 2000s and 2010s
From the late 1990s, countries began replacing analogue broadcasts with digital ones. Digital signals use the airwaves more efficiently, so the same spectrum can carry more channels and, later, high-definition pictures. The United States ended full-power analogue broadcasting on 12 June 2009, and the United Kingdom completed its switchover on 24 October 2012. Many other countries made the change in the same period.
Live TV moves to the internet
Streaming video over the internet was possible in the 1990s, but slow connections kept the picture small and unreliable. That changed as broadband spread in the 2000s. Broadcasters launched their own online players, such as BBC iPlayer in 2007, and began streaming their channels live alongside the regular broadcast. YouTube, founded in 2005, added live streaming in the early 2010s, and many news channels now run official 24/7 streams there.
Free ad-supported streaming television (FAST) services, such as Pluto TV, launched in 2014, recreated the experience of flicking through channels on a connected TV or phone. Paid live TV streaming packages offered an alternative to a cable subscription.
Live TV today
Viewing habits have shifted decisively. According to Nielsen, in May 2025 streaming accounted for 44.8% of TV viewing in the United States, more than broadcast and cable combined for the first time. Yet live television has not disappeared. News, sport, elections, award shows and major public events are still watched live, now as often on a phone or laptop as on a living room set. The way the signal travels has changed from radio waves to satellites to the internet, but the appeal is the same as in 1936: seeing something as it happens.
