In 1927, Ernst Alexanderson of GE made the first demonstration of his television broadcasts[22] at his General Electric Realty Plot home at 1132 Adams Rd, Schenectady, New York. On January 13, 1928, he made what was said to be the first broadcast to the public in the United States[22] on GE's W2XAD: the pictures were picked up on 1.5 square inch (9.7 square centimeter) screens in the homes of four GE executives. The sound was broadcast on GE's WGY (AM).[citation needed]
