This network, known on-screen as "Fox", can now be picked up in over 96% of U.S. households. In 1987 News Corp bought The Herald and Weekly Times Ltd. in Australia, the company that Rupert Murdoch's father had once managed. By 1991, News Corp had amassed huge debts, which forced it to sell many of the American magazine interests it had acquired in the mid-1980s. Much of this debt came from its stake in the Sky Television satellite network in the UK, which incurred massive losses in its early years of operation, which (like many of its business interests) was heavily subsidized with profits from its other holdings until it was able to force rival satellite operator British Satellite Broadcasting to accept a merger on its terms in 1990. (The merged company, BSkyB has dominated the British pay-TV market since.)
