A central tenet of the RIAA/IFPI terror campaign against file downloading has been that file downloading causes the industry to loose billion of dollars a year. This point is hotly debated by many who point out that downloading is more like sampling then buying and has probably resulted in net growth for the industry. However, the myopic, luddite brain-dead response of the music industry has been to ignore the mounting evidence of the negligible impact of file-sharing on music sales. Instead they prefer to sue old ladies and children and further poison their relationship with their customers.
Needless to say these arent the brightest folks in business. Fortunately, our good friends in the Ivory covered halls of academia have been busy crunching numbers and running models to see just what is what. Well the latest in a string of reports from some well lettered individuals is in and the numbers show that file-sharing is likely to have negatively impacted just .7% of CD sales. Ars Technica has the full story and its not good for the labels. You cant argue with science man.
