It's the same as people who watch football matches and other sports matches, they just look at and read every picture and writing that moves on the billboard without caring what it is showing. They are traditional types of gamblers, not online gamblers.
Not entirely true, IMO. If one is a gambler and see stake as a gambling platform, they might be interested to play in online gambling platform for the first time. Gamblers whether online or offline players have their interest piqued when something new platform is introduced.
By traditional gamblers, I mean those who gamble offline will never know every name of the gambling site displayed on the billboard while they are watching a show.
Usually they are gamblers who like lottery gambling without accidentally watching a football match and the team playing the match is the team they like, such as watching the Everton vs Aston Villa match. They don't care what is written on the Everton and Aston Villa jerseys.
Even though the writing on the Everton jersey is the biggest betting site. What is written on the Aston Villa team jersey is also a betting site.
