Nikolay Pultsin wrote the first FBReader; the tool was released for theSharp Zaurus in January 2005, aMaemo port was added in December 2005 for theNokia 770. FBReader has since had binary packages released for many mobile-device platforms and for most major personal computer operating systems.[5]The FBReader name with theFB prefix comes fromFictionBook, an e-book format popular in Russia, the country of FBReader's author.[6]
The original FBReader was written in C++; however, in 2007[7] a fork called FBReaderJ was created, which was written in Java. As the Android platform became available in the following years, this fork became the codebase for the Android software application, while the C++ codebase remained in use for other platforms.[8]
In 2015 the software for all platforms became closed-source: the old open-source code has not been updated since. The Android app was split into free and premium versions, both closed-source, with the premium version adding integrated support forPDF and formachine translation.[9]
For easycross-platform compiling, FBReader uses zlibrary, a cross-platform interface library. It allows recompiling for many platforms while disregarding theGUI-toolkit used.
