This is mainly UK i think. http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/06/11/wcup11.xml £150,000 for a thirty second advertisement during an ITV (uk channel) world cup game. The company garnier who make skin care stuff have alot of ads during the games, most their products are like £10 dont know how the hell they get that money back.
Definitely a lot of money in the game. Adidas expects to sell 15 million of their Teamgeist footballs at £70/ea ($130)!! That's over £1bn grossed from just the Adidas football.
