I am old enough to remember when sports betting was relegated to bookies and casinos. Now, thanks to an ever increasing number of online betting companies, it is an intrinsic part of most sporting events.
Bringing in revenue for governments, broadcasting companies, investors and sports leagues, it is widely available and actively encouraged. More than betting on the outcome of a game or match, one can bet on what will happen on the next play or on the game stats for any given player; in other words, fans can bet on every aspect of their favorite sports. Furthermore, newcomers are enticed with free money in their account to get them started (i.e. hooked).
While many fans might be able to participate without consequence, I suspect a significant percentage become addicted to the thrill of an occasional win and end up losing money that should go to more important obligations in their life; of course, betting company ads always include a number to call for those who succumb to such unfortunate tendencies. Meanwhile, those who invest in the gambling services profit handsomely.
