Mobi format was invented by the French company Mobipocket and was originally used as an ebook format for their MobiPocket Reader application. The company was aquired by Amazon in 2005 and since then mobi format has been used in Amazon's Kindle. The Amazon's eBook formats, including .azw, .azw1, and .azw3, use the MOBI format but incorporate a proprietary DRM scheme to prevent unauthorized users from viewing or copying an eBook that is contained in the MOBI file. Mobi files usually have .mobi extension, or they may have .prc or .pdb extension as the format was originally designed for Palm Pilot PDAs. The extension can be changed by the user to either of the accepted forms.
