News Corp's Australian newspaper websites will go behind paywalls next year, chief executive of the digital division Richard Freudenstein confirmed on Friday.
Speaking to ABC radio, he suggested that the media conglomerate's newspapers -- the Australian, Sydney's Daily Telegraph and Melbourne's Herald Sun -- are likely to adopt the Wall Street Journal (WSJ) model.
The WSJ model has about 50 per cent of free content and the rest as paid for, he added.
He said that News Corp. is not following the company's British model -- adopted for the Times and its sister publication the Sunday Times -- for the Australian websites as the media conglomerate was keen on experimenting with various pay models.
Freudenstein dubbed the Guardian's editor Alan Rusbridger as "naïve" for believing that sites could continue to be free to access.
He said that the UK newspaper was losing its revenue and only existed because of subsidies from other parts of the organisation.
