In the “this could be headed here” department, The Denver Post is now printing ads on its editorial page, according to that city’s alt-weekly, Westword. The first one was from a health care lobbying group, which reported a “significant spike” in visits to its webpage after the ad ran, according to an ad agency quoted by Wesword. The Denver Post is the flagship of MediaNews Group, the chain that owns the Mercury News, Contra Costa Times and other Bay Area dailies.
