People collect all sorts of things, but banner ads are extremely unusual. Tari Akpodiete has 17,000 of them saved to her computer. Website ads for movies, books, porngraphy sites, and lots more. She display them at BannerReport.com, a site that has become a resource for people who design ads, and a bit of an Internet museum. Seeing an ad that caught her fancy one day, Ackpodiete saved it to her hard drive. One thing led to another, and an obsession was born.
