Doc - Top Ten: Eurovision

"The Eurovision Song Contest (French: Concours Eurovision de la Chanson) is an annual competition held among active member countries of the European Broadcasting Union (EBU).
Each member country submits a song to be performed on live television and then casts votes for the other countries' songs to determine the most popular song in the competition. The Contest has been broadcast every year since its inauguration in 1956 and is one of the longest-running television programmes in the world. It is also one of the most watched non-sporting events in the world, with audience figures having been quoted in recent years as anything between 100 million and 600 million internationally. Eurovision has also been broadcast outside Europe to such places as Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Egypt, India, Japan, Jordan, Mexico, New Zealand, the Philippines, South Korea, Taiwan, Thailand, the United States, Uruguay and Venezuela despite the fact that that they do not compete. Since 2000, the Contest has also been broadcast over the Internet, with more than 74,000 people in almost 140 countries having watched the 2006 edition online.
Studies have been made that suggest voting blocs are a major factor, with certain countries tending to form "clusters" or "cliques", sometimes due to sharing similar cultural and/or ethnic communities, by frequently voting for one another, and that these blocs on at least two editions of the contest have crucially affected the result of the competition.
Artists whose international careers were directly launched into the spotlight following their participation and victory at Eurovision include Domenico Modugno, ABBA, and Celine Dion."
