Yahoo Launch Ad Placement Network

Yahoo has launched a self-service ad-placement network that is designed to offer small publishers, including bloggers, access to revenue from contextually relevant advertising, a service already offered by rival Google. Yahoo said the beta version of the expanded Yahoo Publisher Network is aimed at small- and medium-sized Web sites and is currently available only to sites invited to take part. The beta is expected to run at least to the end of this year with further expansions to come.
