What does keep the black dog at bay mean? I wonder whether âblack dogâ is used as a pun with âwinter blueâ in the headline. Is âkeep the black dog at bayâ a well-established idiom?
Although many people claim television was invented by Philo Farnsworth in America, it was actually invented by John Logie Baird, a Scotsman who carried out his research in London England. He first demonstrated his system in 1925 and it was in commercial use by 1929.
John Logie Baird invented and introduced the first TV system in London, England on January 26, 1926. To scan image, Baird used double spiral lenses in this electronic device. The first TV only featured 30 lines, which was one of the reasons why Baird decided to develop an upgraded version.The inventor established a company named Baird Television Development Company. The corporation successfully transmitted a TV signal from London to New York in 1928.he Epsom Derby in 1931 is the first live event that was televised. Baird continued to improve the system until he invented an ultra-short wave electromechanical device in 1932. New models of TV systems created by Baird were launched until 1936.
