There are many ways to watch free tv on PC. There are lots of website that provides this kind of services but some of them are illegal and unstable. Recently, I found a website that collects the youtube live tv channels and other kinds of channels. The website cateorizes the videos by countries, languages, and types. I can find my favorite video easily. And it's legal. Furthermore, the website also support android/ios app so I can watch TV with my smartphone anywhere/anytime. The best thing is it's totally free and legal.
The contents of the website are rich. I really highly recommend the website. Hey!TV Hope you enjoy it!
