Copy-protection Software
The two pieces of copy-protection software at issue in the 2005–2007 scandal were included on over 22 million CDs marketed by Sony BMG, the record company formed by the 2004 merger of Sony and BMG's recorded music divisions. About two million of those CDs, spanning 52 titles, contained First 4 Internet (F4I)'s Extended Copy Protection (XCP), which was installed on Microsoft Windows systems after the user accepted a EULA which didn't mention the software. The remaining 20 million CDs, spanning 50 titles, contained SunnComm's MediaMax CD-3, which was installed on either Microsoft Windows or Mac OS X systems after the user was presented with a EULA, regardless of whether the user accepted it (although Mac OS X prompted the user for confirmation when the software sought to modify the OS).
