What Happened on July 10th

 
Telstar Satellite Launched
Trans-Atlantic television and other communications became a reality as the Telstar communications satellite was launched. A product of AT&T Bell Laboratories, the satellite was the first orbiting international communications satellite that sent information to tracking stations on both sides of the Atlantic Ocean. Initial enthusiasm for making phone calls via the satellite waned after users realized there was a half-second delay as a result of the 25,000-mile transmission path.
