The myth of Amazon's e-book monopoly, in two screenshots

[Commentary] Amazon actually has a huge problem in the e-book market -- people find books through platforms that Apple and Google control.

I assume that's why Amazon CEO Jeff Bezos was so eager to the develop a Fire Phone product. Amazon's original e-book dominance was built on a hardware device, the Kindle, that Amazon controls. But as mobile phones have gotten bigger and tablets have gotten cheaper, Android and iOS products are increasingly viable as reading devices. Kindle books work great on those platforms -- I love the Kindle app on my iPad -- but Amazon has no control over the platform and is at constant risk of getting squeezed out.
