The first television was invented in 1925 by John Logie Baird. He demonstrated the first working model at Selfridges department store in London, where spectators were able to view blurry, but recognizable, letters on the screen.
While John Logie Baird is credited with creating the first working model, he could not have achieved this without the work of late 19th-century scientists like Henri Becquerel, who discovered that electricity could be converted into light, and Ferdinand Braun, who invented the cathode ray tube. Prior to Baird's demonstration, over 50 attempts had been made to invent television by a number of nations, all with well-staffed and well-funded laboratories. Logie Baird did not have this luxury and had to sell his own business, as well as borrow from friends and use scraps, to complete his invention.
