Amazon business and revenue model
I recommend anyone studying Amazon checks the latest Amazon revenue and business strategies from their SEC filings / Investor relations. The annual filings to give a great summary of eBay business and revenue models.
A good summary of the latest business model initiatives is always available in the latest Amazon annual report summary. The latest report includes a great vision for Digital Agility (reprinted from 1997 in their latest annual report) showing testing of business models that many businesses don't yet have. Amazon explain:
"We will continue to measure our programs and the effectiveness of our investments analytically, to jettison those that do not provide acceptable returns, and to step up our investment in those that work best. We will continue to learn from both our successes and our failures".
They go on to explain that business models are tested from a long-term perspective, showing the mindset of CEO Jeff Bezos:
We will continue to make investment decisions in light of long-term market leadership considerations rather than short-term profitability considerations or short-term Wall Street reactions.
The latest example of innovation in their business model is the 2014 launch of the Fire phone. Which while an undistinguished as an Android smartphone features innovation in its 3D dynamic perspective and can recognize over 100 million all told movies, video games and CDs to other products. Naturally owners can read product details for these items, add them to their Wish List, and order them on Amazon.com.
