Igital revolution in the music industry

Write a paper on how the music industry became all digital over the years and now the singers do not make money through selling Cds and cassettes because people can download there music through the internet. In fact the money is made through the concerts. Now this industry has become digital. First tape recorders were used than CD rooms were used and now Aux cable and Bluetooth devices are used to play music. Technology is changing and it very quickly out dates the existing technology. To stay in the business we have to use new technology and keep changing ourselves with it so that it does not outdate us. The paper should majorly show the research on music industry and its history over the years .
