Terapeak created an eBay "top-ten list" of movies, albums, games and books based on volume of items sold on eBay. The lists are updated monthly and are available on the Terapeak site at no charge.

The top movies on eBay for the month of February, according to the Terapeak list, included The Little Mermaid, The Grudge, The Notebook and Shark Tale. Top books included. The Broker, The Da Vinci Code, Honeymoon, and The South Beach Diet. The top album for February was Confessions: Special Edition (Usher), and the top game was Grand Theft Auto San Andreas.

Clicking on a title on the lists takes you to Terapeak's Smart Shopper, which does real-time analysis on eBay listings and shows you the best deals on those items on eBay.

Terapeak licenses eBay market data and provides eBay users with a subscription-based service to research selling prices, sell-through rates and other eBay metrics by keyword or category.
