Publishers around the world have been waiting for a convincing sign that readers are willing to pay for digital content. Many are known to have well advanced paywall plans in place but have lacked the assurance to introduce a charge for fear of driving away readers.

The New York Times’ recent announcement that it now has more than 450,000 digital subscribers coupled with its plans move to reduce by half the number of free articles readers can access online each month beginning in April suggests growing confidence in digital subscriptions.

Will the NYT’s success be the trigger for action from other publishers?

Experts will assess which subscription models are working and report on what the world’s pioneering publications are planning in a special digital session at the annual congress of the World Association of Newspapers and News Publishers in Kiev from 2-5 September.

But digital is not just about paywalls, and this session will also look at the latest developments in tablet and mobile publishing as well as feature some of the industry’s best paid-for apps.
