Maynard, Mass.—Monster, the parent company of job site monster.com, Monday announced an alliance with four newspapers aimed at expanding its advertising arrangements with traditional media companies. The move comes just a week after search engine Yahoo! announced a similar move with more than 150 newspapers in which Yahoo's HotJobs site will work together with the newspapers on classified job ads. Google, Yahoo's chief rival, has also launched an ad-sharing plan with dozens of newspapers. Monster’s partnerships are with Freedom Communications, a privately held media company in California whose flagship newspaper is the Orange County Register; North Jersey Media Group, which publishes The Record of Bergen County; the Wilkes-Barre (Pa.) Times Leader; and the Honolulu Star-Bulletin. Under the deals, Monster will build and maintain job-search Web sites for its newspaper partners and also integrate the listings with its global recruitment database, which is accessible at Monster.com.
