Interesting Advertising information

I read this article with interesting information. In the United States the cost-per-impression of a promotional product is half a cent ($0.005). Ad specialties deliver a better cost-per-impression than most other media.
• 83% in the U.S. indicated they can identify the advertiser on a promotional item they own.
• People ages 45 to 54 own the most promo products.
• 41% of U.S. respondents say their opinion of an advertiser is more favorable after receiving a promotional product.
