Baird was a prolific inventor, one of the leading pioneers of television. In 1923 he transmitted his first shadowy televised images in a rented room in Hastings. In 1926 he publicly demonstrated the world?s first recognisable television pictures. Two years later he transmitted the first trans-Atlantic television pictures from London to New York. He also developed colour television, stereoscopic (3D) television, and 'Noctovision' - television in darkness using infra-red light. Baird?s electro-mechanical television system was broadcast by the BBC from 1929-35. However, by early 1937 the BBC chose to adopt the rival Marconi-EMI television system. Baird?s later career was spent developing cinema television, stereoscopic television and high definition colour television.
