Gambling is a significant global industry, which is worth around 0.6% of world trade, that is, around US$ 384 billion; and gambling on the outcome of sports events is a very popular pastime for millions of people around the world, who combine a bet with watching and enjoying their favourite sports. But, like any other human activity, sports betting is open to corruption and improper influence from unscrupulous sports persons, bookmakers and others. Sports betting in the last ten years or so has developed and changed quite fundamentally with the advent of modern technology not least the omnipresence of the Internet and the rise of on-line sports betting. This book covers the law and policy on sports betting in more than forty countries around the world whose economic and social development, history and culture are quite different. Several chapters deal with the United States of America. This book also includes a review of sports betting under European Union (EU) Law. The book appears in the ASSER International Sports Law Series, under the editorship of Dr. Robert Siekmann, Dr. Janwillem Soek and Marco van der Harst LL.M.
