While online casinos, especially to the younger generation of people around the world, may be seen as very old technology, the fact is that the technology is fewer than 15 years old. Looking back at the history of gambling, it can be argued that the invention of online casinos is one of the biggest things in the history to ever happen to gambling. In Nevada, gambling was legalised in the early 1930’s, which in fact created Las Vegas as we know it today and is the biggest event in the history of gambling. Over the past 10 years, the growth of online casino has been astounding. While exact numbers are difficult to get a hold of, it is estimated that the amount of money generated from online casinos was about 1 billion back in 1997. In 2006, it is estimated that the business took in over 10 billion in total.
