As projected by MediaNews Group CEO Dean Singleton back in September 2009, and updatd in November,  the media firm will put up content pay walls at two of its newspaper sites this May.

MediaNews Group Inc. will start charging a fee for some articles on two of its newspapers’ Web sites in May. Bloomberg.com reported that the pay system will be similar to what the New York Times recently adopted. Content each of the two papers determine to be premium will be accessible only with an undisclosed fee, though print subscribers will still pay nothing or at least less. Coupons, puzzles, designated columns and investigate reporting will likely incur a charge.The first 25 premium articles each month will be free to all, however.

“Most of our content will remain free,” MediaNews president Joseph Lodovic told Bloomberg. “Once subscribed, the reader will have access to all premium across MediaNews Group.”

The Denver, Colo.-based media group will use the new Journalism Online LLC Press+ product  to help process payments for its sites.

MediaNews Group owns 16 daily and 100 non-daily newspapers, a CBS TV affiliate station in Anchorage, AK, and four radio stations in Texas.
