Piano Media has announced that it is raising the price of the national paywall it established in Slovakia last year, a move its CEO Tomas Bella says in a release had been the plan for once the platform was “accepted”.

The decision to raise the price follows the launch of the company’s second joint national paywall in Slovenia last month, involving nine publishers in the country.

In Slovakia the price will go up from 1 March, the release adds, from €.99 to €1.39 a week, €2.90 to €3.90 a month and from €29 to €39 for a year.

With steady revenue and reader growth established, Piano’s pricing structure moves into its next development phase after gaining broad acceptance by Slovakia’s digital readers.

In the release Bella adds: “The number of our subscribers is still going up. More and more people are telling us that they were against the concept at first but now have gotten used to the idea and already feel comfortable with paying.”

The company confirmed in the release that it “is in negotiations with publishers in 11 European countries and has plans to launch in more European markets by the end of 2012”.
