Who invented cassette tape technology?
Mizrahi music
It is a widely accepted fact by now that the invention of the recordable cassette by the Philips Corporation and the commercial cassette distribution network in the Tel Aviv train station had a large impact on the popularity of Mediterranean Israeli music. Cassettes allowed the Mizrahi population create and distribute their own music within their communities. They also allowed for more musical integration. One could have Umm Kulthum and a neighbor who is an emerging singer.
Cassette tapes were a predominant factor in the growth of Mediterranean Israeli music in the 1970s. After first being a favorite at community celebrations, such as weddings and birthdays, the recording of one particular wedding party became a desired commodity in the Mizrahi ma'abarot ("transit camp"). These cassettes are what caused ethnomusicologist Amy Horowitz to start researching this blossoming new music style.
Tape recorder
American audio engineer John T. Mullin and entertainer Bing Crosby were key players in the commercial development of magnetic tape. Mullin served in the U.S. Army Signal Corps and was posted to Paris in the final months of WWII. His unit was assigned to find out everything they could about German radio and electronics, including the investigation of claims that the Germans had been experimenting with high-energy directed radio beams as a means of disabling the electrical systems of aircraft. Mullin's unit soon amassed a collection of hundreds of low-quality magnetic dictating machines, but it was a chance visit to a studio at Bad Nauheim near Frankfurt while investigating radio beam rumours, that yielded the real prize.
