Introduction
AZW is Amazon’s proprietary eBook format derived from MOBI, optimized for Kindle devices and apps. It has become a standard in digital publishing, particularly for books distributed through Amazon’s Kindle store.
Historical Context
Amazon launched the Kindle in 2007, and with it, the AZW format was introduced. This format is built upon the MOBI format, which Amazon acquired from Mobipocket in 2005. AZW files utilize DRM (Digital Rights Management) to prevent unauthorized copying and distribution, making it a preferred format for authors and publishers concerned about intellectual property protection.
