TL;DR: The Australian Open is streaming games for free on YouTube. The catch is that the players, court, and ball are all 3D generated. They and constructed in near-real time using cameras and video tracking software.
The loophole allows the Australian Open to show a version of live events at the tournament on its own channels, despite having sold lucrative exclusive broadcast rights to partners across the globe.

I was at the airport and there was an NBA game on tv and on another tv were Disney characters playing basketball. It took me a while to realize it was the same game.
As a software developer (previously game developer) I was very impressed with how good the tracking was. Not just position, but complicated moves, dribbling the ball between their legs, facial animations, everything with less than a 10 second lag.
The Disney version was way more fun to watch.
