Sports betting is a relatively new industry in the US.

Until 2018 you could only legally bet on sports in the state on Nevada, the home to Las Vegas.

New Jersey was the first state to legalise sports betting six years ago and since then, a total of 38 states across America have done the same.

Hannah Mullane looks at how the industry has grown so rapidly and discusses the consequences of the industry which has been allowed to evolve with very little regulation.
