The US network is being spun off.

But for instance they will own Sky - the biggest commercial broadcaster in Europe, and the UK's second biggest ISP...

In addition to this, Sky Sports is pretty much the only game in town in the UK when it comes to sports. Sky hold an insane amount of power in football, to the point where if they want a game to be played at a different time/day the fixture will change. The sheer amount of money in the Premier League today is down to Sky.

This is a linear market that I think Disney will be really interested in. It's an area where Netflix haven't entered (to my knowledge), and it's an area that no one can seem to do well.

BT Sport has made some in-roads, but Sky is definitely a dominate player.

IIRC, it's the only only pay-TV provider available in large parts of the UK (cable TV is only available in about 60% of the country last time I checked).
