Let us count the ways Amazon.com continues to push the envelope. This year it launched niche stores selling flowers and fine art, worked with Condé Nast to offer one-click payments for magazine subscriptions and let shoppers curate products via the Pinterest-like Collections. But what really caught our fancy is its marriage of shipping and digital content. The 8-year-old Amazon Prime has grown up, offering not only two-day free shipping for $79 a year, but also access to more than 40,000 film and TV titles. Though suspected of running Prime at a loss, Amazon takes in about $1,200 annually from its estimated 10 million Prime members, double the $600 for the average non-Prime Amazon consumer, according to Morningstar Inc. and Consumer Intelligence Research Partners.
