Conde Nast Publications Inc., the second-largest U.S. magazine publisher, cut staff at its Internet network as ad prospects grow less predictable.
A spokeswoman declined to say how many people would lose their jobs.
The company's CondeNet runs Wired.com, Epicurious.com and Concierge.com, the companion site of Conde Nast Traveler magazine.
"We are adjusting all costs to prepare for slower revenue growth," Conde Nast said. The spokeswoman said 2008 revenue would be "slightly" higher than last year.
