Sony BMG Music Entertainment's botched attempt to stop unauthorised music copying has cost the company another US$4.25 million (NZ$6 million).
Two days after reaching settlements worth a combined total of US$1.5 million with Texas and California, on Thursday, Sony agreed to pay another 40 states the money to end investigations into its use of two copy protection programs: First 4 Internet's XCP (extended copy protection), and MediaMax, written by SunnComm International.
In a statement, Sony says it is pleased with Thursday's settlements.
More than 12 million Sony BMG CDs shipped with this software last year, according to a statement from the Massachusetts Attorney General.
Sony's trouble began in late 2005, when a computer science researcher disclosed that XCP used dangerous "rootkit" techniques to cloak itself after installation.
Later, investigators found that even users who declined to install the MediaMax program would have software placed on their computers, and one version of the program created a security issue, the Massachusetts statement said.
Sony has reportedly also reached a tentative settlement with the US Federal Trade Commission in the matter, although nothing relating to that investigation was announced on Thursday. Sony settled a class-action lawsuit over the software in May.
As with the California and Texas agreements, residents of the 40 states that settled with Sony are entitled to up to US$175 in refunds for damages that may have been caused to their computers. The settlements also limit the ways that Sony can use copy protection software in the future and require that the company notify consumers if it uses this kind of software.
Sony has set up a website with information for consumers on the matter. It is expected to eventually include information on how to file a claim under these latest settlements.
