Experimental TV sets installedIn 1928, three television sets were installed by RCA and GE in homes in Schenectady, New York. American inventor E.F.W. Alexanderson demonstrated the first home television receiver which delivered a poor and unsteady picture only 1.5 inches square. The picture, with 48 lines at 16 frames per second, was transmitted over 2XAF on 37.8 meters and the sound was transmitted over WGY radio station. The sets were in the homes of Alexanderson and two board members. On 28 May 1928, the first television station WGY began broadcasting regular programs on Tuesday, Thursday, and Friday afternoons from 1:30 to 3:30 pm, using 24 lines. Sets were built and distributed by General Electric in Schenectady. |
