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.
