Okay, I'm an old guy and just joining the modern world -- I bought a smart TV -- LOL. It's got so many features and such, I'm busy watching EVERYTHING -- Since I spend much of my life sitting in chairs with my legs elevated.

Here's my question: what streaming service(s) play Euro-BB games?

EuroLeague has its own TV network which includes an online streaming service (EuroCup games included):

But talking about national and regional leagues across Europe, there is no one place where you can see whatever you want because broadcasting differs for every league.

But if you are not allergic to the occasionally bad video quality of the transmission, a large number of European leagues and competitions are covered by various FREE streaming services like this one: https://basketball.sportshub.stream/
