By sending Amazon’s (AMZN) stock to all-time highs during the past year, Bezos effectively hushed critics who worried that the company was spending too much on technology and shipping discounts. Now, the company he founded 14 years ago is firmly focused on exactly the kind of new ventures that Bezos relishes. Whether it’s the Kindle e-book or cloud computing services aimed at businesses that want to store data and their operations on Amazon’s massive server farms, Bezos is committed to developing new kinds of revenue streams for the digital future.
