Pay as you watch TV and smaller bundles purely for sports channels certainly seems the way forward. Likewise with the BT Sport model (although for how long they can keep their prices relatively low I'm not sure).
I'm not so sure how much it will revamp their sales and viewing figures, once people switch off it's hard to get them back. Either way the long term effect could be negative for PL clubs. There's just no way Sky and BT can sustain the amount they spend on football, it's just not feasible when tv is gradually declining. It's basically just one growing bubble that's waiting to burst.
And likewise to some here it seems, when choices have to be made subscribing for sky sports at £40+ a month just isn't worth it. I happily pay for Bt sport as it's quite cheap and it's easy to sort out tv and broadband + a home phone in one go. It's not as if it's hard to watch games online, plus the big games I prefer to watch at a bar anyway.
