They haven't disappeared as much as sport gambling is willing to pay a lot of money, because they make a lot of money. The business side of the sport dictates that the sports gambling money will win out. I'd argue it is a societal good to limit the exposure... much like cigarette ads getting banned. I don't care if people smoke, but it shouldn't be promoted. Frankly I'd say the same of any vices out there... booze, gambling, etc.
Though as we hit an election cycle here in the states, sports is about to be bombarded by political ads too. So each commercial break will be Draft Kings -> Trump/Kamala -> Bet 365 -> Senate Race -> Groove Subaru... then upon returning and update to the odds brought to you by FanDuel.
