context_page_description: The Sony Reader was a line of e-book readers manufactured by Sony, who produced the first commercial E Ink e-reader with the Sony Librie in 2004. It used an electronic paper display developed by E Ink Corporation, was viewable in direct sunlight, required no power to maintain a static image, and was usable in portrait or landscape orientation.
  Sony sold e-books for the Reader from the Sony eBook Library in the US, UK, Japan, Germany, Austria, Canada and was reported to be coming to France, Italy and Spain starting in early 2012. The Reader also could display Adobe PDFs, ePub format, RSS newsfeeds, JPEGs, and Sony's proprietary BBeB format. Some Readers could play MP3 and unencrypted AAC audio files.
  Compatibility with Adobe digital rights management protected PDF and ePub files allowed Sony Reader owners to borrow ebooks from lending libraries in many countries.
  The DRM rules of the Reader allowed any purchased e-book to be read on up to six devices, at least one of which must be a personal computer running Windows or Mac OS X.
