“In the U.S. this century, gambling has become more wholly legitimized, released from the confines of Atlantic City and Las Vegas and into the broader culture. Gambling advertisements litter the country, and more than 20 states now allow casinos, compared to just nine in 2001. Roughly the same number have legalized online sports betting and more people are pushing for legal online casinos as well.” The combination of legalized sports betting and the ubiquity of the casino in your pocket is not going to end well. The Rise of Mobile Gambling Is Leaving People Ruined and Unable to Quit. How mainstream is gambling these days, particularly sports betting? Just ask Disney.
