Reuter's Susan Butler wrote an in-depth account of the RIAA.'s efforts to curb piracy that is well worth reading. Whether their efforts will have any long lasting effect is debatable. By all accounts, the music industry is doing well. It's the record / CD business that's broken. The business model hasn't worked since Armageddon arrived: broadband, high quality compression, and inexpensive storage.
Despite the RIAA's efforts, data suggest that demand for pirated content remains strong. A recent NPD Group report estimates that 19% of U.S. Internet subscribers 13 and older download free music from P2P services, barely less than the 20% reported when the RIAA began its user litigation campaign in 2003.
As noted in these pages, similar efforts by the MPAA are inaccurate. Researchers recently got them to accuse three laser printers of piracy. Perhaps toasters and coke machines are next.
