Historical Data	On September 30, 1951, relay systems carried television from coast to coast, and for the first time in history, TV viewers on the West Coast were able to watch "live" video shows originating in the east, and vice versa. A television link between Los Angeles and the east moved a step closer to reality as the first telephone message zipped through the skies between 107 microwave towers that zigzagged 3,000 miles across the nation to connect New York and San Francisco by radio relay. The towers were about 30 miles apart and were in line of sight of each other, since beams travel in straight lines and do not follow earth's curvature. The microwaves are so-called because they are only three inches in length compared with 1,000-foot radio waves in the idle of the standard broadcast band.
Description	Photograph caption dated August 17, 1951 reads, "Heretofore confined only to West Coast audiences, programs like this one on ABC-KECA TV will be sent zipping over the continent to untold millions of viewers." Note: Pictured, Jack Gregson interviewing "King" Wayne Hughes.
