During the spring of 1925, John Logie Baird gave a series of public demonstrations in Selfridges department store in London’s Oxford Street that showed how television might eventually be realized. Though only capable of showing simple shapes, his demonstration system was notable in having the subject conventionally floodlit, and the televised image reproduced on a separate, wirelessly connected, display [1].
