Known as Everybody's Nintendo Channel in Japan, it features videos, player reviews, and DS demos.
When WiiWare launches in North America on May 12th it will be joined by the release of the Nintendo Channel. The service launched in Japan in November of last year, under the title "Everybody's Nintendo Channel."
The new channel will feature video features, user recommendations, images, release schedules, and DS demos that the Wii can wirelessly upload to Nintendo's handheld. The channel will also feature integration with Nintendo's WiiWare service in the form of user recommendations. After they've purchased and played a WiiWare game for at least an hour, players will be able to review the game on the Nintendo Channel for others to see. Steven Rodriguez wrote in depth impressions of the Japanese version back when it launched.
The Nintendo Channel will be a free download from the Wii Shop Channel.
