I just found an interesting idea about how to improve the effectiveness of banners. The thing is just to turn it interactive instead of being only a box with information. They named it "Nike+ Challenge Men vs. Women" and it works like this:
- You put a banner against men on a website for women
- You put a banner agains women on a website for men
- Let them discuss on real time like in a chat mode
And this is the result (Youtube, 1min):
Other brands could work perfectly with this ad mode.
