Mobipocket SA is a French company incorporated in March 2000 that created the codice_1 e-book file format and produces the Mobipocket Reader software for mobile phones, personal digital assistants (PDA) and desktop operating systems. 

The Mobipocket software package is free and consists of various publishing and reading tools for PDAs, smartphones, mobile phones, the e-readers Kindle and iLiad, and applications on devices using Symbian, Windows, Palm OS, Java ME and Psion. 

On October 31, 2016, Amazon permanently shut down the Mobipocket website and servers. 

Mobipocket.com was bought by Amazon.com in 2005. Amazon's acquisition was believed to be a result of Adobe Systems’ announcement that it would no longer sell its eBook packaging and serving software. 

An alpha release of the Java-based version of the Mobipocket reader was made available for cellphones on June 30, 2008. There is also a reader for desktop computers running Microsoft Windows, which also works with computers running Mac OS X and Linux using Wine. 

It has been widely reported that since Amazon's acquisition of Mobipocket, software support, user support, and platform growth was ended. In December 2011, it was reported that Amazon officially notified the book publishers that it was ending support for Mobipocket. The status of Mobipocket Digital Rights Management (DRM) content previously purchased by users continues to be unclear since no other ebook reader supports its proprietary DRM method.
