U.S. News & World Report will cease printing its monthly magazine in 2011, according to an internal memo from editor Brian Kelly posted on the journalism website Poynter.org's Romanesko blog.

Famous for its annual rankings on the best colleges, hospitals, personal finance and a slew of other topics, the magazine had already slipped from a weekly to a bi-weekly and then a monthly over the last two years.

Its circulation plunged last year to 1,269,260 from 1,721,377 the year before, Magazine Publishers of America estimated.

The rankings issues will continue to be published in-print, along with four special topic issues, but the rest of the publication's content will only be available online, the memo said.

Its last regular print edition will be next month.

"All of us at U.S. News Media Group have been aggressively responding to the changing habits in the media marketplace," Kelly wrote. "These latest moves will accelerate our ability to grow our online businesses and position ourselves to take advantage of the emerging platforms for distributing information."

A call to the magazine's public relations department went unanswered Friday afternoon.
