Do you remember the days of Michael Parkinson when film stars, writers, comedians, etc., came on the programme and just had an interesting chat?
Nowadays, if such a person is a guest on any programme, it is not to have an interesting chat but to market: a newly released book or film, a theatre production they're in, a business they've started, etc. etc. I've also noticed that such guests often drop into the conversation a favourite product they use. On top of this, I assume they get paid for appearing on the programme.
Michael Parkinson himself commented that now "chat shows" are just a marketing opportunity for the invited guests. (It's a pity that he also joined the club by fronting adverts for questionable life insurance products).
Everything is about competition and profit and there is no reason why footballers should be immune to this drive for more and more money.
It is unfair that a loyal football supporter should have to pay so much money to watch his team, but I think it's even more unfair that the necessities of life - food, water, housing, heating - are subject to the same ever-increasing pressure for profit.
