Last summer, Nintendo's 3D television service "Itsu no Ma ni Terebi" launched in Japan. It featured short two-minute 3D clips that were free and exclusive to the 3DS.
Today, Nintendo announced that the service is ending in Japan on June 20. The 3DS, however, will continue intermitted distribution of 3D videos for 3DS owners—a good thing.
To be honest, I only checked Isu no Ma ni Terebi out a few times. The novelty wore off pretty quick.
