RUPERT Murdoch will shut iPad newspaper The Daily from December 15, admitting it has failed to win enough subscribers to make the online subscription venture viable.

News Corp said The Daily, which was unveiled in February 2011, would ''live on in other channels'' with technology and some staff being integrated into the New York Post.

The Daily was losing $US30 million a year and amassed about 100,000 subscriptions, according to an open email in June from founding editor-in-chief Jesse Angelo. Mr Angelo, a close friend of James Murdoch, will take the role of publisher at the New York Post, where he was previously executive editor.

''From its launch, The Daily was a bold experiment in digital publishing and an amazing vehicle for innovation,'' Mr Murdoch said. ''Unfortunately, our experience was that we could not find a large enough audience quickly enough to convince us the business model was sustainable in the long term.''

The Daily, which operated a subscription model at US99¢ a week, or $US39.99 a year, needed about 500,000 subscriptions to break even.

Mr Murdoch's move came amid a flurry of activity by publishers to attempt to take advantage of the rise of tablet and smartphone technology. Days after his announcement, online news and opinion site The Huffington Post was acquired by AOL for $US315 million. GUARDIAN
