Slashdot notes that The Wall Street Journal Online is making more money for Dow Jones than their print publications. From the New York Post:

Earnings plunged by 54 percent at the newspaper's parent Dow Jones & Co., with its fledgling online operations earning more money for the first time than the flagship Journal and the weekly Barron's.

Is this a portend of things to come? It makes sense to me that academic journals would consider moving to online subscriptions to increase subscription revenue while also being able to cut costs of subscriptions for their members. Libraries could pay extra to receive print on demand versions of the journals or choose to subscribe to electronic bibliographic database services as they are already doing (which seems to be the trend for journal collections). Will the future of journals be online?
