Could you tell me what were the most popular and the best paid logos in 2006. Maybe you know some web sites were I could find some statistics about this?
Thank you.

Businessweek, along with Interbrand conducts an annual survey and does research on the 100 Best Brands in the World (http://images.businessweek.com/ss/06/07/top_brands/index_01.htm). It offers some great insight into not only the effectiveness of good branding, but details on changes to positioning, logo's, etc.
