Music Sales May Not be Hurt By Online Piracy
The first report ever done that looks at the effect of free music download services available on the Internet and record sales revenue has found no correlation between the two. The study found that free music downloads had such a miniscule statistically insignificant impact on record sales that it was akin to zero. This definitely is not the result that law makers, the Justice Department or record industry would have expected. The only worse news for them would have been that free downloads increased revenue.
