The Sumo Association has not been a big proponent of fans publishing videos. I hope this changes. The NFL is also very protective of its rights over video footage. I believe this is why the sport does not spread beyond the US. The NBA, on the other hand, has a much wider international audience. Today, I found this very interesting article about the NBA promoting fan videos. It makes the sport more engaging for fans and allows the sport to grow via social media…Web 2.0. Sumo was really made for Vine. I hope fans will be able to publish and share loops via Vine or YouTube a bit more freely.
