Television, colloquially known as telly, was a system that allowed people to view broadcast plays, news, drama and comedy. It was a major source of entertainment and information on Earth from the mid 20th century onwards.
In 1066, the Monk believed that his meddling with history to change the course of the Battle of Hastings would lead to Shakespeare putting the play Hamlet on television. The First Doctor responded that he knew the medium. (TV: "Checkmate")
The First Doctor claimed that television sets first appeared on Earth in the 1930s. (AUDIO: Upstairs) The television was invented by John Logie Baird during the 1920s and was commonly known as a televisor in its earliest years. As they were still experimental devices, very few people owned one. UK Prime Minister of the era, Ramsay MacDonald, (AUDIO: Storm Warning) was among these few, as were the family of Josie Laws McRae, as her father was a lawyer who worked for the Logie Baird company in Long Acre. On 14 July 1930, the BBC broadcast a television adaptation of The Man with the Flower in His Mouth by Luigi Pirandello. This was the first television drama to be produced in the United Kingdom. Provided that it was successful, the BBC was considering producing a television adaptation of Black Orchid by George Cranleigh. (PROSE: The Wheel of Ice)
By the early 1950s, the sets were already highly developed, although advances would continue to be made. The Wire tried to regain a physical body by using an Alexandra Palace television transmission of the coronation of Queen Elizabeth II on 2 June 1953, but the Tenth Doctor managed to trap her in a video cassette. (TV: The Idiot's Lantern)
In the far future, television was still a popular pastime. Violent television was much more common than before in such places as the planet Varos and in the Fourth Great and Bountiful Human Empire. (TV: Vengeance on Varos, Bad Wolf)
Television existed on Skaro towards the end of the Thousand Year War. Captain Croag and the Highland Rangers was a Kaled propaganda television series. Davros watched it as a child, as did his elder half-sister Yarvell. (AUDIO: Guilt)
