Get N or get out.

This rich media ad for the Nintendo Wii is very clever. It's not at all obtrusive and annoying. I just saw the little 'Wii' logo next to a comment on my Xanga and thought, "What is this?" I hovered my mouse over it and noticed that it was an ad for the Wii. I think the most effective part of it was that I felt I was entirely in control. No one asked me to see the ad. I didn't even have to look at it if I didn't want to because it's so small. But I did want to look at it because it sparked my curiosity.
Clicking on the ad takes you to a page hosted by Xanga. But it's not a static page. It's just a regular Xanga entry about the Wii, where people can comment. I think it's a brave step that Nintendo took to allow all sorts of users to provide feedback for not just this product but essentially their whole line of products. I only wish the controller on the left side of the screen did something fun.
