Technical Developments of the 40's & 50's With the increase in the success of record sales came the need to introduce methods to diminish manufacturing costs in order to increase profit margins. Nowhere was this need more prevalent than with the independent record companies in the industry for they had the most to gain let alone survive. After the demise of Germany, German technology made its way across the Atlantic to America. One of these technical break through was the ability to store audio information on magnetic tape.
