In 1928 Charles Jenkins was granted the first commercial television license in the United States and In July 2, 1928 Jenkins Television Corporation started to operate W3XK, the first TV station.[2] first aired from Jenkins Labs in Washington and from 1929 on from Wheaton, Maryland, five nights a week. At first, the station could only send silhouette images due to its narrow bandwidth, but that was soon rectified and real black-and-white images were transmitted.

In December 1928, Charles Jenkins founded in New Jersey the Jenkins Television Corporation to produce and manufacture Radiovisors. In March 1932, Jenkins Television Corporation was liquidated and its assets acquired by Lee de Forest Radio Corporation. Within months, the De Forest company went bankrupt and the assets were bought by RCA stopping all work on electromechanical television.
