New York ? The Wall Street Journal’s glossy magazine, WSJ., is increasing its frequency and circulation starting in March.

The magazine will boost its U.S. circulation to about 1.5 million from 800,000 and publish six times a year, up from four. The magazine will maintain its 160,000 circulation outside of the U.S.

The move appears designed to appeal to advertisers, some of whom have spread their ads to other Journal properties after first advertising with the magazine.

The Wall Street Journal and WSJ. magazine are divisions of News Corp.

WSJ. launched in September 2008 and currently is distributed to Journal subscribers in quarterly weekend editions in large U.S. markets. Starting next year, the magazine will be made available to all U.S. subscribers and newsstands.
