Printing company RR Donnelley said today it has acquired Journalism Online, a company aimed at helping news papers monetize their web content.

Financial terms of the deal were not released.

Three veteran media executives are behind Journalism Online including Steven Brill, founder of Court TV, Gordon Crovitz, a former publisher of The Wall Street Journal, and Leo Hindery, a former chief executive of AT&T Broadband.

Journalism Online created a payment platform called “Press+” that allows newspapers and magazines to charge readers for access to online content via a password-protected website. Press+ allows publishers to offer users a mix of options for subscribing to premium content, including metered and mobile/tablet access, improved site functionality, and out-of-market access.

“Our publishing customers continue to develop multi-channel advertising and editorial strategies and Press+ provides a valuable tool for monetizing content,” said Thomas J. Quinlan III, RR Donnelley’s President and Chief Executive Officer.

“We provide solutions across the entire breadth of the publishing supply chain, from content creation and digital asset management through subscription solicitations, processing and renewals. Press+ enhances our offering and opens new avenues for publishers to generate incremental subscription and advertising revenue.”
