Sony's eBook store is eschewing its own proprietary format in favour of adopting the open EPUB format. By end of 2009, Sony’ll only sell EPUB books in its store, and will’ve dropped its proprietary DRM entirely in favor of Adobe's CS4 server side copy protection. After the change, books bought from Sony’s online store’ll be readable on growing constellation of other readers. EPUB (an XML-based eBook standard used by the International Digital Publishing Forum) is most widely supported formats in eBook readers. "A world of proprietary formats and DRMs creates silos and limits overall market growth." Consumers should not’ve to worry about which device works with which store. With a common format and common content protection solution (DRM), they’ll be able to shop around for the content they want regardless of where they get it or what device they use," Steve Haber said.
