I think the Apple, Google, Netflix even MS links would make sense. They have all got into the content game via tech platforms.
Without knowing the financial details; when you are spending £5-7billion, you are looking at returns in 10-15 years' time. I am sure the EPL model will change before that.
Take the little Wrexham experiment -- the two boys discovered how antiquated the custodians of football, below the EPL were. They were able to bend them then a little to suit their agenda. They have the publicity off the Netflix series -- and wanted to then leverage technology like IPTV to then stream direct. Even they could figure it out.
There is less of an incentive for the NFL and the MLB since they are primarily for the domestic audience. NBA is a much more global sport/content than the above two.
We have moved into a new technology model -- you have the ability to remove the middleman now. It wont happen overnight. But I see United streaming direct to United fans in 10years time with some sort of hybrid model. The technology has been there the past 5-8 years already. Maybe clubs like Burnley or Palace have a bigger share of the TV pot whilst clubs like United get more leeway to stream direct. Afterall MUTV already exist , they just need to pump up the resources like global bandwidth management, bigger production crew etc.
Sports is content. And Content is king.
Most of all, successful content is just very difficult to create or find.
