or because it started with the increasingly difficult global COVID-19 situation, and more and more countries are advising or even banning their citizens from leaving their homes, and people are spending more and more time at home with their phones and internet now. And this is also the reason why the online gaming business is booming, because people have nowhere to go.
I feel like even without the pandemic and people getting stuck in their homes, online gambling would still become a huge success/booming. it would have only been a matter of time before gamblers/people start finding out how convenient online gambling is. anyway, that being said, the pandemic still has a huge impact on online gambling.
and that is why, pandemic seemed to be the driving force why there's a boost in online gambling. remember when people were looking for some entertainment over the internet, online gambling was one of the industries that got their attention during that period, and so with the rise of these online casinos and sportsbooks.
