The biggest industries on the internet...who has some stats on that?
 

Does anyone have any stats on what the biggest INTERNET industries are in order, and how much revenue they generate?

That's a complex answer since you're not distinguishing whether just a company that operates on the Net only like Amazon or a company like Microsoft which owns some of the biggest Net properties but also operates in the retail world.

Here are the top sectors if this helps in your quest.

On-line retailing, marketing and advertising

Security

News and information providers

ISP's and search engines

Internet applications and telephony

Online brokers and banks.
