Internet Gambling Legal gambling generates a half trillion dollars in revenue in this country every year.
Law enforcement believes much more than that is wagered illegally.
And the next frontier for illegal gambling just may be the Internet. On a good day, a single race track like Golden Gate Fields generates several million dollars worth of wagers. And while most people lose, it's the chance of winning that keeps people betting. Horse racing pales next to casino gambling when it comes to pulling money out of bettors' hands. But mix gambling with the Internet, and you could be talking something really big.
