A Brief History of ePub Formats
Over the years, several formats have
been developed to facilitate digital reading. Here's a brief overview:
Plain Text and PDF: The Pioneers
Before dedicated eBook formats arrived, there was plain
text (.txt). This format was simple and could be read on any computer, making
it one of the earliest ways to digitally store books. Then came PDF (Portable Document Format) developed by Adobe in the 90's, which was aimed to present documents consistently regardless of the software,
hardware, or OS. It soon became a popular choice for eBooks, especially for
academic and business publications due to its ability to retain layout, fonts,
and graphics.
PalmDOC (1990s) This early format was designed for Palm Pilot PDAs. It
was simple and could compress text, making it a great fit for devices with
limited storage.
EPUB (2007) Developed by the International Digital Publishing Forum,
EPUB (Electronic Publication) quickly became a standard for eBooks. Flexible,
reflowable, and open standard, it can adjust text according to the screen size,
making it suitable for various devices. EPUB3, the latest version, also
supports multimedia, interactivity, and enhanced navigation.
MOBI (2000) This format was designed for the Mobipocket eBook reader but
gained significant traction when Amazon bought the company and used the format
(with modifications) for its Kindle devices. Today, Amazon's
eBooks use a derivative of MOBI called AZW.
FB2 (2004) FictionBook is a format popular in Russia. It's XML-based and
mainly designed for fictional literature, containing only the book's text and
no software or formatting.
Microsoft's LIT (2000) Designed for the Microsoft Reader application, it
provided a good reading experience with ClearType technology. However, it
couldn’t compete with rising stars like EPUB and MOBI and was discontinued in
2011.
Apple’s iBooks (2010) Apple introduced its proprietary format based on
EPUB but enhanced with multimedia and interactivity capabilities. It works
exclusively on Apple devices.
KFX (2015) Amazon's next-gen eBook format offers features like enhanced
typesetting and rich formatting options. It's been designed to provide a better
reading experience on Kindle devices.
With the proliferation of tablets and smartphones, there was a push for
more interactive eBook formats, especially for educational and children's
books. These formats, like EPUB3, include multimedia elements, animations,
interactive quizzes, and more, making the reading experience more engaging and
dynamic. The future holds more flexibility and
interactivity. With the growing popularity of audiobooks, we might also see
formats that seamlessly combine text, audio, and perhaps even virtual or
augmented reality elements.
