"Why did jazz become a dominant popular music genre in the 1920s and rock 'n' roll in the 1950s? Why did heavy metal, punk rock and hiphop find their way from sub-cultures to the established music industry? What are the effects of new communication technologies and the Internet on the creation of music in the early 21st century? These and other questions are answered by Peter Tschmuck through an integrated model of creativity and innovation that is based on an international history of music industry since Thomas A. Edison invented the phonograph in 1877. Thus, the history of the music industry is described in full detail."--BOOK JACKET.
