Commercial gambling ads will be available only in the countries who supported gambling to grow and probably your government let this happen because they admitted gambling as industry and can be good source tax for them but besides all of it i think they will also thinking the risk behind it especially i read your post that there was casinos near to high school locations and it's very risky to childrens at there will attempts to gambling because casinos is too easy to be access
I think we know that the gambling business is very profitable for entrepreneurs. millions of dollars in profits can be generated in 1 night. of course to change the rules in a country is very easy if they want to lobby. because all rules have a price? thats why the growth of the gambling business is accelerating
I believe on this, if you have the money even if youre not qualified to put up a business you can still get the permit because this is a profitable business, and someone will also benefit if you make good profit. It will continue to rise until everyone tries to gamble because of so many casinos around your place.
