Tape recording

In 1938, a tape recorder was used for the first time in the U.S. to send a radio broadcast. The sapphire stylus engraved Millertapeused was invented by James Arthur Miller of the Miller Broadcasting Company. A 1,000 foot section of this tape could carry a 15-min program, which could be editted by cutting. This first program using this sound tape was transmitted by WQXR, the Interstate Broadcasting Company, in New York City from 6:30pm to 7 pm.
