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, France, Italy, and Spain. The Reader also could display Adobe PDFs, ePub format, RSS newsfeeds, JPEGs, and Sony's proprietary BBeB ("BroadBand eBook") format. Some Readers could play MP3 and unencrypted AAC audio files. Compatibility with Adobe digital rights management (DRM) 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. Although the owner could not share purchased eBooks on others' devices and accounts, the ability to register five Readers to a single account and share books accordingly was a possible workaround. On August 1, 2014, Sony announced that it would not make another consumer e-reader. In late 2014, Sony released the Sony Digital Paper DPTS1 - which only views PDFs and has a stylus for making notes - aimed at professional business users. Models and availability Ten models were produced. The PRS-500 (PRS standing for Portable Reader System) was made available in the United States in September 2006. On 1 November 2006, Readers went on display and for sale at Borders bookstores throughout the US. Borders had an exclusive contract for the Reader until the end of 2006. From April 2007, Sony Reader has been sold in the US by multiple merchants, including Fry's Electronics, Costco, Borders and Best Buy. The eBook Store from Sony is only available to US or Canadian residents or to customers who purchased a US-model reader with bundled eBook Store credit. On July 24, 2007, Sony announced that the PRS-505 Reader would be available in the UK with a launch date of September 3, 2008. Waterstone's is the official retail partner and the Reader is available at selected stores such as Argos, Sony Centres and Dixons; while a red edition is available exclusively from John Lewis.
