as reported in the New York Post:
Amazon.com shares hit a new record yesterday after it reported better-than-expected quarterly profit, fueled by the growth of higher-margin businesses during the fiercely competitive holiday quarter.
The world's largest Internet retailer said that its cloud-computing services, video content sales and aggressive expansion in e-books helped increase profitability.
Chief Executive Jeff Bezos highlighted the Kindle's e-book business, calling it a multibillion-dollar category that grew about 70 percent in 2012. Its traditional physical book business rose about 5 percent in the same period, he noted.
