The deal means that all 19 of the Times Co.'s papers -- including The New York Times and Boston Globe -- will co-brand their sites with Monster and add its proprietary search tools and content as well as its national listings.
"The combination of technology, reach and expertise created by this strategic alliance is extraordinary," Times CEO Janet L. Robinson said in a statement. "Together with Monster, the New York Times Co. will significantly increase our presence in the online recruitment space as we continue to provide quality solutions and considerable value for employers and job seekers."
In the statement, Monster CEO William Pastore added: "The alliance significantly advances Monster's strategy to provide highly localized online recruitment and career services, allowing Monster to leverage its expertise and full range of solutions in conjunction with the Times Co.'s award-winning local news outlets and powerful distribution presence."
Until last year, both Monster and Yahoo's HotJobs largely eschewed newspaper partnerships, leaving them to rival CareerBuilder, which was founded by mega-publishers Tribune, Knight-Ridder and Gannett.
But the acquisition by McClatchy Co. and subsequent partial breakup of Knight-Ridder last year sent three former CareerBuilder papers -- The Philadelphia Inquirer, Philadelphia Daily News and Akron Beacon Journal -- to Monster.
Monster also struck a deal with Orange County Register parent Freedom Communications and the privately held St. Petersburg Times.
In November, Yahoo signed deals with seven major publishers -- including Hearst, Belo, Scripps and MediaNews -- that were reportedly unhappy that CareerBuilder was raising the cut of ad revenue it requires from participating papers.
Newspaper analyst John Morton called the fragmentation "inevitable."
"It's positive that newspapers are realizing that they are in a huge transformation," Mr. Morton said. "They're viewing these [web] guys as partners, and not just a threat."
