I'm not a specialist in economics so I can't really critic any details in the article, but it seems as if the money may run out sooner rather than later. Sky and BT won't be able to continue with the vast sums that they're spending on TV rights.
Sky are having to completely revamp their sports channels, which shows that they're worried about the slump in viewing figures. It may be quite a way away, but surely sky will have to cut back on its spending on football somewhere in the future.
If this all turns out to be true, wouldn't clubs like us be even more in danger? Surely clubs with rich owners be better able to cope should the bubble burst (assuming they would want to cover the costs)
