An Apple E-Book Rule Tightens
By CLAIRE CAIN MILLER February 1, 2011
When you see people flipping through e-books on iPads or iPhones, there is a good chance they bought the books through Amazon.com, not Apple.
Now, Apple wants to change that.
Apple confirmed Tuesday that it would require app developers that sell e-books outside of their iPad and iPhone apps - through a Web site, for example - to also sell the books inside those apps. And purchases that originate in the app must be made through Apple, which keeps a 30 percent cut.
Apple said it was newly enforcing an existing rule, one that will force Amazon, Sony, Google and other e-book sellers to change the way their apps work.
