What year did John Loge Baird showcase his invention?

Answer 1

In his first attempts to develop a working television system, Baird experimented with the Nipkow disk, and in February 1924 demonstrated to the Radio Times that a semi-mechanical analogue television system was possible by transmitting moving silhouette images, such as his fingers wiggling, in his London laboratory. Baird gave the first public demonstration of moving silhouette images by television at Selfridges department store in London in a three-week series of demonstrations beginning on March 25, 1925.
