I hope it's enforced by the EU at this rate so it hits everywhere.
Currently in Bulgaria: the league is the "efbet A group", both teams are sponsored by one of bet365, Betano, PalmsBet or efbet, the stadium is named "efbet Arena", shirt sponsors are 777-bet or some online casino app, the scrolling banners are of betting companies and the other sponsor that gets their logo to appear in the centre of the pitch at intervals is another betting company.
Might appear to be something very comical but currently, other than stadiums, it's the exact same crapshoot in the Prem as well - scrolling banners/ads are of betting, SkyBet are the official sponsors of half the things, Stake/888/whatever scummy sponsor on shirts (or shirts AND sleeves, just in case you miss it).
Wonder why people get addicted, no reason really.
