Short answers, pulled from the story.
BBC Television officially launched its regular service at 3:00pm on the 2nd of November 1936, from a converted wing of Alexandra Palace in London. The opening programme featured Major G. C. Tryon, the Postmaster General of the United Kingdom.
The last programme transmitted before the wartime closure on the 1st of September 1939 was the Mickey Mouse cartoon Mickey's Gala Premier from 1933. This directly contradicted the popular belief that broadcasting had been suspended before the cartoon ended.
BBC Two became the first television channel in Europe to broadcast regularly in colour on the 1st of July 1967, using the West German PAL system. BBC One and ITV followed with 625-line colour broadcasts simultaneously on the 15th of November 1969.
BBC Television's domestic channels are funded by a television licence fee that viewers are required to pay annually, including those who watch real-time streams or catch-up services online or on mobile. The BBC's international television channels are funded by advertisements and subscription.
Following the 2016 Licence Fee settlement, BBC Television was split into two divisions. In-house production became BBC Studios under Mark Linsey, while channels, commissioning, BBC Sport, and BBC iPlayer were renamed BBC Content under Charlotte Moore. As a result, BBC Television as a formal corporate entity ceased to exist internally.
John Logie Baird set up the Baird Television Development Company in 1926 and made the first experimental television broadcast for the BBC on the 30th of September 1929, from the BBC's studio in Long Acre, London. His electromechanical system broadcast 30-line images and continued via the BBC until June 1932, though the Baird system was ultimately discontinued by closedown at 22:00 on the 30th of January 1937 after proving too cumbersome compared to the all-electronic Marconi-E.M.I. system.
