In a move to make its electronic book store compatible with multiple devices and its Sony Reader e-reader devices open to multiple sources for content, Sony has announced plans to convert the Sony eBook Store to the open format EPub e-book standard by the end of the year and adopt Adobe Content Server 4 for copy protecting downloadable e-books. "Our intention is to lead by example," said Steve Haber, president of Sony's Digital Reading Business Division, in a statement.
