Sports betting has changed dramatically over the last decade or so, with the rise of smartphones and live data, which has revolutionised the sports gambling industry.
Before the rise of online bookmakers, you had to go to a betting shop and make your prediction, before the match or race had begun, and usually well in advance of the event itself.
Nowadays, many punters prefer to look at live betting sites, and bet in-play, as you can get a read on the event in the early stages of a match or race, before committing to the bet. The popularity of live sports betting sites has risen with the increase of live streaming too.
