Universal service has a pivotal role in market liberalization and competition on both sides of the Atlantic. It is central to the European thinking on markets and public service and is an inevitable element of market liberalization and sectoral competition rules. The universal service aims at preserving the public service in a competitive environment. The paper analyzes this cornerstone of the European thinking from a comparative and trans-sectoral perspective, demonstrating that the concept of universal services should be fundamentally re-conceptualized in EU electronic communications and energy regulation.
