Yahoo! Publisher Network

Yahoo! Publisher Network launched a new self-serve platform that will provide small- and medium-sized web publishers with easy access to Yahoo! advertising and content. We're very excited about our new offering, not only because it will enable a broader set of publishers to generate revenue from their sites, but also because it can offer publishers access to many of Yahoo!'s other products and properties.
The Yahoo! Publisher Network self-serve platform is currently available as an invitation-only beta."
