Murdoch lent credence to that theory, taking to Twitter to criticise "Oz politics!" and question how the cross-continent broadband - which the conservative opposition wants to scale back in cost and scope - could be paid for in Australia's AAA-rated but slowing economy. "News Corp hates the government's National Broadband Network (NBN). The company has formed a view that it poses a threat to the business model of by far its most important asset in Australia, the Foxtel cable TV monopoly," wrote columnist Paul Sheehan for the rival Fairfax newspaper group. Telecommunications analysts don't doubt Labor's NBN, rolling fibre cable into almost every home, threatens Murdoch's most important Australian asset, Foxtel, jointly owned with phone giant Telstra and near unchallenged in pay TV.
