On the 10th anniversary of the passage of the Digital Millennium Copyright Act (commonly referred to as the DMCA), Public Knowledge takes a close look at what effect the DMCA has had on innovators, artists and new business models. Part two features Mark Richert, Director of Public Policy for the American Foundation for the Blind. In both 2002 and 2005, the American Foundation for the Blind filed for exemptions to the DMCA, so that blind and visually impaired users could use eBooks in conjunction with accessibility software.
