Rupert Murdoch once hijacked rugby league. Now he could end up with nothing.

With his $84 million Gulfstream jet parked at Sydney Airport on Monday, the media mogul again had staff on edge.

Imagine the look, then, on the 84-year-old's face when he stepped off the plane to learn that Channel Nine had usurped News' Fox Sports in hatching a $925 million deal for rugby league from 2018.

Two decades after Murdoch's Super League tried to hijack the entire code, all for the sake of television "product", it could end up with nothing at all.

Without rugby league, how many subscribers would Foxtel lose?
