A short-form video service, in the style of the previously announced SpotPass, will be available in late May when a system update will be available for the Nintendo 3DS.
The service acts much like a portable Nintendo Channel and will bring exclusive content to 3DS with Nintendo-moderated selections such as comedy clips and music videos.
