Super Bowl 50 is the biggest sporting event in history and it will be broadcasted on the internet on Sunday night.
It will mark the first time that people can watch the game on the web, but a lot of people will not be able to see it because of geo-blocking.
It will also be the biggest internet video game tournament ever.
It is not the only major sporting event to have to contend with geo-blocking.
The first edition of the Wimbledon Championship last year was blocked by a Chinese state-owned company called Wuhan Technology Co. It also had a significant impact on other major sporting events, including the Olympics.
