It was already common enough in the US, but it's downright rare compared to how common it is in the UK or other places where it's legal. Hull, Stoke, West Ham, and Manchester City come to mind -- all big soccer teams who have/had bookmakers emblazoned on their uniforms as the main sponsor. I'm sure that if the US makes sports betting legal we'll see a huge influx of betting companies, apps, etc. Like you said, most of it was handled by foreign companies, but now they'll be able to advertise and grow in the US in earnest.
