Amazon.com recently announced that Kindle e-books are finally outselling the printed editions. For every 100 paper books sold, Amazon sells 105 e-books, even when excluding those given away for free. While Amazon hasn’t released exact sales numbers, it has sold three times the amount of Kindle books since last year. In other news, LinkedIn recently launched its Initial Public Offering with shares reaching as high as $122. The company has a valuation near $8 billion and is the largest Internet I.P.O. since Google. The popularity of LinkedIn’s IPO is good news for privately traded tech companies looking to go public. And finally, Verizon will no longer offer its flat-rate unlimited data plan starting this summer. Instead, the company will move to tiered pricing that costs more if you are a heavy data user. Verizon hopes to offer data family plans that would finally cover data use on multiple devices.
