The way viewers pay to watch on demand services is to change radically in Poland.

Gazeta Prawna reports that six companies – Cyfrowy Polsat, Grupa Onet, Grupa Wirtualna Polska, Iplex, Cinemand and ipla – are among a group, together accounting for over 80% of a market worth around PLN150 million (€37.5 million) a year, that have entered into an agreement designed to protect minors.

Starting from today (October 15) viewers wishing to watch content categorised as being for adults will be required to provide their credit card details.

Studies by PBI and Gemius show that around 1.6 million internet users in Poland aged 7-18 currently access online adult content.

At present, around 16 million Poles watch on demand services. However, the use of credit cards is actually falling, down from a peak of 10.9 million in 2009 to today’s total of around 6.1 million.
