Amazon.com has continued to show an increasing commitment to the e-book market with the revealation that last month it bought a French company that sells e-books and “software for reading them on hand-held computers and wireless phones,” according to a brief Bloomberg News report in the Tacoma News Tribune. The revelation that Amazon bought the French based Mobipocket.com on March 30 was made when an S.E.C. filing was made public. The news comes on the heels of last week’s news — as in this report from the Web Host Industry Review — that Amazon had purchased Booksurge, “a printing fulfillment company that provides thousands of books users can print on demand.” The report referred to that acquisition as “the latest in a series of moves by Amazon to diversify its revenue sources and compete with rivals such as Ebay and Overstock.com.”
