The gradual “penetration” of an innovative, digitally-oriented information society, in the scope of the actual convergence among telecommunications, broadcasting and information technology, create primary opportunities for access and exploitation of Public Sector Information (PSI), in the context of a fully competitive and liberalised European electronic communications market. There are now significant challenges on the scene, for improving mutual communication between public sector and private companies, thus creating chances for exploiting new opportunities, to the benefit of the broader European market(s). However, the non-existence of an appropriate legal framework governing the conditions and/or terms for the commercial use of PSI constitutes a serious drawback for any serious attempt towards evolution, and for an effective development of a European e-Communications market. Recent European regulatory-oriented policies have established and supported suitable measures and provisions, to ensure access to PSI for all interested parties and for their “free” circulation among Member States. In the context of the suggested contribution we examine current European harmonization regulatory measures, towards creating transparency and legal security for all market players involved in the wider content market, thus contributing to growth.
