Although e-books have gradually gained popularity, formats are so diversified that both consumers and manufactures alike are finding a path suitable for themselves among these format competition.
The simplest e-book format is, undoubtedly, the txt, which, however, failed to be commercialized in the market as a result of the code problems and the incapability of having pictures. For sure, we can transfer the materials into txt format, reading them in mobile or other intelligent devices.
Supporting many a device, pdf is also a good e-book format, with users getting used to it. But readers need to adjust the screen resolution when reading with different screen sizes. Pdf’s merit is that it supports password verification, allowing the publishers to receive money via account from the content.
Currently, the electronic products of the e-book giant Amazon’s kindle are broadly seen, especially in the international market, which includes the exclusive e-book machine for hardware, e-book software for computer and other e-book software in intelligent mobiles or portable devices such as Android, iPhone, iPod and iPad.
Kindle’s format is .zaw and also supports voice function. As long as Amazon is there, Kindle, seen from the long-term perspective, may walk steadily and own a certain share of the market.
The cross-platform and highly support of other e-book’s hardware and software makes EPUB format earn the next spot. Even Android or iPad can support EPUB, except Kindle’s device and software. The layout is not as good as that of pdf. In my perspective, this open-source e-book standard will stand out in the future among other e-book formats.
As for publishers, betting on EPUB or Kindle shall be an obvious strategy.
