Lausanne, the Swiss city IOC (International Olympic Committee) President Juan Antonio Samaranch honored with the title "Olympic capital" in 1994, is now the administrative capital of world sport. The past century has presented Olympism with many challenges and that continues to be the case today; the issues may have changed, but they are no less numerous. Controversies over phony amateurism, the two Chinas and the creation of a modern Olympia have been resolved, only to be replaced by questions of governance, compliance, strategy, responsible management, the size of the Games, the scarcity of bids and new forms of doping and corruption. All these themes are examined in the articles that make up this book published about 100 years after the establishment of the IOC’s headquarters in Lausanne. This book was originally published as a special edition of Sport in Society.
