no need to wait for the future. If you watch the news of the local variety at least in my area, most of the advertisements are for betting. Same with sports.
At the moment, those gambling ads are pervasive and, sadly, "normal".
Now, remember to watch sky sports you have to pay something like £50 a month.
They then saturate half the program with adverts of people gambling.
When I was a kid in the 80s and 90s, gambling was something James Bond did at Monte-Carlo with a vodka martini, or something my grandad did with the horses in a seedy shop next to the chippie. The only thing about gambling most people saw was some "pools" thing that was mentioned after the football results.
Now people spend £600 a year to be bombarded by messages telling them it's normal to get your phone out and put £10 on who will score the next goal when watching a football game. Maybe it is normal now, but it didn't used to be 20 years ago.
In the 1990s I remember there were slot machines in some pubs, where men would put in £1 or so and very occasionally win a huge pile of 10p coins.
Last time I checked the Annual Report, sky's revenue was something like 90% subscription, 10% adverts.
Ireland and the UK have an exception to the rule banning gambling apps, and their in-app payments. So you could gamble with money from your phone bill/prepay credit. I'd be interested to learn the history of that.
