As promised, here is a slightly longer reply.
SOS have certainly discussed this idea previously. It's been a fairly public and long held view that the money flowing in to the game should be re-directed (or at least some of it) to help other 'stakeholders' in the game - supporters, grassroots etc.
Now with the growth in TV income, range of partnerships with different brands, alongside the growing value of these sponsorships and partnerships, I think it is fair to say that the importance of some revenue streams has diminished, or certainly the need to keep increasing it. One of those is ticket pricing, particularly given how the club use us supporters as a marketing tool and how these sponsors and partners invest because they want to be a part of what we are.
I think there are two ways you can do. The first is to say that a % or a set amount of revenue (league wide or club specific, or both) should be set aside to act as a subsidy for ticket prices. The second is that ,as pointed out in this thread, you get a specific sponsor for fans. There are questions and issues to arise from that - who chooses the sponsor, what does the sponsor want that may not cost the club anything, how much would a sponsor pay, is it that it's only this sponsors money that should be used to subsidise prices or should we still be asking for a bit of all the other riches.
An example I suppose is Barclay's sponsorship of the league. They embarked on their big #ThankYou campaign, one of the things I said to the Premier League at a meeting with them was they would have been better to use all the money spent on that - consultants, tv ads, marketing etc - and just put it in a pot for the people they tried to say thank you to make those coach trips and tickets more affordable.
All this though depends on the willingness currently of the clubs across the league, collectively and individually. Obviously we have the Ticket Working Group at Liverpool and I am personally hopeful that this can deliver. Let's see what the next few months bring, particularly with all the attention and pressure the new tv deal has brought.
