( CNN ) -- This morning in New York City , Rupert Murdoch held a press event announcing the launch of The Daily , the world 's first iPad-only `` newspaper . '' While I listened to the streaming audio , I was scanning the news -- and I spotted a headline that should probably make News Corp. nervous about its new venture : Apple blocks Sony e-book app . Is Kindle next ? First , a bit about The Daily , per today 's announcement : . According to News Corp , iPad owners can subscribe to The Daily with one click , at a weekly rate of 99 cents . An annual subscription costs $ 39.99 . The publication also will display paid advertising . Furthermore , Murdoch confirmed that the iPad will probably be the only provider for The Daily for this year and next year . Eventually News Corp. will be developing editions for all tablet platforms , but for right now , it 's effectively an iPad exclusive -- which means News Corp. is relying heavily on the terms of the deal it 's worked out with Apple to make the economics of this venture pay off . Meanwhile , there 's that Apple/Sony/Kindle flap , which was sparked largely by this New York Times article . In a nutshell , Apple rejected Sony 's new iPhone/iPad e-reader app from its app store in part because that app would jump readers out into the mobile browser in order to buy e-books . This strategy skirts Apple 's considerable 30 % cut for in-app purchases -- and it 's how Amazon 's popular Kindle app has handled purchases from the beginning . Apple claims that this is not a bait-and-switch rule change . The Times ran this quote from an Apple spokesperson Trudy Muller : . `` We have not changed our developer terms or guidelines . ... We are now requiring that if an app offers customers the ability to purchase books outside of the app , that the same option is also available to customers from within the app with in-app purchase . '' Which is where Apple takes its 30 % cut . I 'm sure News Corp. has worked out with Apple a percentage of subscription revenues that go to Apple . And that 's fair , since Apple is providing distribution for The Daily . But what if those terms were to effectively change without notice ? This Sony decision could very likely be a red flag that Apple is willing to change the rules of how it does business without notice , in ways that could affect all of its app providers . News Corp. has invested lavishly in The Daily , reportedly $ 30 million , including a staff of 120 and prime Manhattan office space . They 're betting heavily that The Daily will pay off big . But if I were Rupert Murdoch -- or Amazon , for that matter -- right now I would be afraid for my iOS-dependent ventures . Very afraid . It might be a good idea for News Corp. to bump up the development schedule for its Android edition .
