Who first made the television..?

In April 1925, a small, rather unkempt young man sat on a stand In a London department store, tinkering with an outlandish piece of apparatus which comprised a tea chest, an empty biscuit box and several hat boxes, darning needles, bicycle lamp lenses, valves, discarded electric motors, piano wire, glue, string and sealing wax. He was John Logie Baird, the inventor of television, who had been engaged by the store owner Gordon Selfridge to spend three weeks conducting his experiments in public. Shoppers who paused to watch this noval attraction of the archetype inventor at work were invited to peer through a frame at a distinct image of the letter H flickering on a tiny screen. They did not know it, but those shoppers were the world’s first television viewers. Baird’s technical developments and the parallel research that was going on in America and Britain were already making their own crude receivers when in July 1928, the Daven Corporation of Newark, New Jersay, advertised the first commercially produced television set for sale. Station WGY had already begun transmitting an experimental service of three half-hour programmes a week in May to watchers in Schenectady, New York. On September 11, 1928, the first television play was presented. The following year Baird began an experimental service in London, for which Televisors, as they were called, were available at 25 guineas. The screen was only the size of cigarette card, but could be enlarged to postcard size witha magnifier.
