More than two years after Google launched AdSense, Yahoo! today will unveil a beta version of its own network for small and mid-size publishers. Yahoo! plans to invite about 2,000 smaller publishers
into the new offering, Yahoo! Publisher Network, before expanding further by the end of the year, said Will Johnson, general manager-vice president of Yahoo! Publisher Network Online. At launch, the
program is designed for publishers whose sites receive fewer than 20 million page views per month, said Johnson. The initial publishers will represent a wide range of sites, including e-commerce,
travel and car verticals, and Web logs. To date, Yahoo! has been testing the program via its own employees who have blogs. -- Wendy Davis
