All of these sites now offer robust hotel, restaurant, travel, local attraction information and reviews targeted to individual locations or ZIP Codes in the United States.

The driver for this product evolution is Marchex's Open List ( Open List is Marchex's search technology and user-generated content platform that offers a deep and targeted aggregation of vertical and local content.

As Marchex extends its Open List technology and content aggregation platform into additional verticals in the coming months, Marchex will augment the content on these Web sites with additional proprietary content.

Marchex believes that the extension of its search technology and content platform to its network of Web sites, including the ZIP Code Web sites, will result in greater usage and monetization over time.

"We are able to accomplish this by extending our content and search functionality to our Web sites - enabling us to effectively treat each ZIP Code domain as a search keyword and pre- populate the Web page with locally-targeted information. The net result is that our Web sites are becoming rich sources of useful, local content, which benefits online users as well as advertisers who want to reach a local audience."
