Overall, gambling has had a rough time in the US. Now, each state has the authority to decide whether they should allow this form of gambling or not. The federal Professional and Amateur Sports Protection Act from 1992 was the one that used to forbid states from legalizing sports betting and it only took two decades to bring it down. Currently, a large number of states have legalized this form of gambling. As of yet, it is only fully legal in Nevada and Delaware but more are on the way. As of May 2018, however, every state has the right to make sports betting legal within its jurisdiction.
Until recently, sports betting was illegal in all states of America, with the exception of only four – Nevada, Montana, Oregon and Delaware.
