It'd be good to see an actual study into the impact removing it would have on lower league teams.
I find it hard to imagine that the number of people who would opt to attend a lower league game rather than watching the PL game online, listening to the game on the radio or just doing any of the thousands of non-football things you could do to pass time at 3pm on a Saturday instead is all that large.
Also don't the games before and after the blackout impact attendance anyway? How easy is it to watch a game that lasts until around 2.30 and still make an entirely different game by 3.00? Or attend a 3pm game and still be home in time to see the 5.30 kick off?
But even if we accept that a significant number of people do attend lower league games because of the blackout, surely that spells long-term trouble for those lower league clubs? As time goes on and the percentage of the football audience who are internet-literate enough to circumvent the rule increases while the world becomes more and more connected, an enforced blackout becomes a more and more ineffective measure. Because as workable ideas go, a blackout within the UK of something that is so widely broadcast everywhere outside the UK seems ever-increasingly out of touch with how the world actually works.
