The Wire Recording Corporation of America introduced a new product called Wire Way. It was sold for $149.50 at the time. The use of magnetic tape for sound recording originated around 1930. In the beginning it was made of paper. The Minnesota Mining & Manufacturing Company (3M) company replaced paper by plastic.
