Bing Crosby agree to audition tape recorders brought in by Jack Mullin and Richard Ranger record Crosby's Philco radio show. Bing Crosby was a big proponent of tape recording. He did not like having to perform his radio broadcasts twice a day, once for the East Coast of the United States and again a few hours later for the West Coast. He figured that if it were recorded (and edited to remove any bloopers or to add different advertisers), he could perform just once.
