One of the reasons it has a higher penetration is that the UK doesn't have anti-siphoning provisions. The long term effect of this legislative scsheme has been to prop up free to air TV INB Australia at the expense of the sports. You seem, wedded to FTA broadcasters. Whilst you support such a scheme, you will wind up with the dross they serve up, which is the lowest cost crap they think they can get away with.
Go to the USA, NBA, NFL, NHL, most of its games are behind paywalls. yet people sign up for subscription TV services there and its sports have some of the greatest TV revenues around. FTA networks there, due to the competition, know they can't just do low budget crap shows if they want viewers and to keep up advertising revenues. Whilst this scheme persists in Australia, it condemns broadcasting to its mediocrity as the FTA networks no incentive to change.
Anyway, I'll leave it there as I think we're straying away from the main part of the topic (even though it has been interesting to discuss

).
