There's an article in Folio magazine online that provides additional
information about the switch to monthly, including "In 2008, U.S. News
saw ad pages fall a staggering 32.4 percent," at
http://www.foliomag.com/2009/will-u-s-news-weekly-work.

FYI, if you're interested in what's happening in the magazine publishing
business, two of the best resources are www.foliomag.com and
www.magazine.org, the web site of the Magazine Publishers of America.
