This volume makes an important contribution to debates about American interactions with Europe in the Twentieth Century. It interrogates current understandings of �Americanisation� and aims to produce new and fruitful departures for future research and discussion. The approach adopted uses the broadest possible view of American influence, encompassing the whole of the micro-economic sphere, and including not only companies, but also consumers and business cultures in general. Taken together, the individual chapters confirm the importance of the US as a reference point for European businesses and consumers.

Above all, they reinforce the view that �Americanisation� was a social phenomenon, involving real people in specific contexts, whether at company, industry or societal level, and motives that ranged all the way from the idealistic to the venal. Ce volume apporte une contribution importante au d�bat sur les interactions entre l�Am�rique et l�Europe au xxe si�cle. Il pose des interrogations sur le sens courant de �Am�ricanisation� et voudrait offrir de nouveaux et fructueux points de d�part pour de futures recherches et discussions. L�approche choisie utilise la vision la plus large possible de l�influence am�ricaine, englobant l�ensemble de la sph�re micro-�conomique et abordant non seulement les entreprises, mais aussi la culture des consommateurs et des entreprises en g�n�ral. Pris comme un ensemble, les diff�rents chapitres de cet ouvrage confirment l�importance des �tats-Unis comme point de r�f�rence pour les entrepreneurs et les consommateurs europ�ens. Simultan�ment, ils apportent un �clairage nouveau sur la complexit� du processus d�Am�ricanisation qui fut toujours plus�
