In short
On 2 November 1936, the BBC launched the world's first scheduled high-definition television service from its transmitter at Alexandra Palace in London. The broadcast marked the practical arrival of television as a medium, ending decades of experimental tinkering and establishing a template for how moving pictures would reach ordinary homes.
How it unfolded.
The five-minute version
What actually happened.
The world's first scheduled, high-definition television programmes were broadcast on 2 November 1936 by the British Broadcasting Corporation. They had been preceded by a number of low-definition BBC test broadcasts, as well as a 180-line Deutscher Fernseh Rundfunk service, from Berlin, since March 1935.
