Abstract
The gradual transfer of regulatory functions from national states to those of the European Union together with the establishment of the single market have all contributed to the Europeanization of the business lobby. Yet few could have envisaged the rapidity with which firms' have developed their political skills and subtlety, let alone the important role they would play in Europe. This article explores how the large firm has come to play such a prominent role in EU public policy making and compares and contrasts European development with the American experience.
