The will be difficult for newspaper publishers to ignore. The industry’s trade magazine, Editor & Publisher is moving from weekly to monthly publication, moving its news to the Web and using print for features, analysis, and commentary.

Steve Outing (an E&P columnist) notes that this is part of a long-term trend in magazine publishing. The Net killed weeklies years ago, and we’re just waiting for the bodies to drop. All the computer weeklies have been struggling to find a reason to exist for years.

How much longer can newspapers ignore the impact of the Web on their own publications? I’m still waiting for the first big daily to drop stock price listings.
