Radiolympia
Radiolympia, also known as the Radio Show, was a pioneering exhibition of radio equipment, and latterly television equipment, held annually at Olympia in London, England, in the 1920s to 1940s, except for a period of interruption during World War II.
The first such exhibition was held in 1926.
On 26 August 1936, the first high-definition standard television transmission was made in a test by the BBC from the exhibition.
The record attendance was 238,000 in 1934.
