Do you think internet as only a larger network of computers and servers. No there is a big business behind it and very large amount of money is flowing. What is the value of a domain name? we can buy www.yourname???.com type domain for just 10 -5 USDs. But there is unbelievable amount of value for premium domains [ex. www.business.com, www.flowers.com, www.income.com, .... etc] Recenlty I have seen on sedo.com that www.pizza.com is featured for 999,999 USDs.
