The loss of income should put an end to reality shows, sorry, but i just can’t see that happening.
I myself have no interest in horseracing, but one day in the year during a local meet i will place a few bets, i don’t consider this to be gambling, but paying to be entertained as i have created an interest in the outcome. The same can be said for placing a bet on a rugby match i would otherwise be neutral on. That i occassionly/rarely cover some of an outings costs this way is merely a bonus.
There is no amount that would be enough to create an interest in reality tv for me, but as 6rant6 says, “To each his own”.
