An interesting article published on Business Wire today quotes a recent report from Forrester Research about the growing popularity of music downloads and streaming services. Specifically, the report looks at what this means for the future of physical media, such as CDs and DVDs. “The shift from physical media will halt the music industry’s slide and create new revenues for movie companies, but it will wreak havoc with retailers like Tower Records and Blockbuster. As a result, we’re about to see a massive power shift in the entertainment industry,” said Josh Bernoff, principal analyst at Forrester.
