Websites who provide the basic "buy and sell" principle have flourished.
Look at Ebay.
Another crazy website that has made lots of money is the free, community reliant Wikipedia.
The one true thing that makes money on the World Wide Web is Internet online poker.
It is our love affair with gambling that continues to rake in the money for us (some of the time) and the online casino house (most of the time).
What is Internet online poker? Well, it's basically poker without having to travel all the way to Vegas.
There are no walls, no bouncers and no visible distractions in this world.
Internet online poker is poker played right in your homes, with real money.
You see, playing poker online is not a new concept.
It is just another vehicle for the sport of poker to attract new players into the game.
That's the appeal of playing poker with your computer to the younger generation: easy access to the game and they can learn the game by themselves through free tutorials for online poker sites.
Since online poker is like the real-life poker, the old patrons of casino houses can play alongside the computer techies.
Who says you can't teach an old dog new tricks? Playing Texas Hold Em on Internet poker rooms is as hip and popular today as it was years ago.
Now the next question is how will Internet online poker make me enough money? The answer is simple, by playing various poker games online.
This is not a scam.
You can really double your earnings by playing Internet online poker rather than heading off to the "brick and mortar casino" houses.
Here's the trick.
Internet online poker is played the same way as any regular poker except now you are allowed to play multiple tables.
The key to increase your winning is by betting on a low limit.
While playing poker in a casino can only allow you to play in one table, playing online poker takes away the physical barrier and gives you the option to view three to ten games simultaneous in one screen.
There are no secrets to it.
Just play smart and you will be sure to double your winnings by the time the online poker tournament is over.
That is, unless lady Luck decides to pass you by.
Another advantage of playing Internet online poker is the increase in the number of hands you can play.
The usual casino house had a dealer and could only play 30 hands per hour.
When you remove the human weakness from the equation and add in technology, there is a dramatic increase in the number of hands played.
An Internet online poker game can deal 60 to 80 hands per hour! This is basically the gambler's dream come true.
Internet online poker is user-friendly, it's also a professional's recruitment arena.
How did that happen? Well, every year online poker rooms hold their annual tournaments called satellites.
And instead of just winning money, the winners can get an entry to real-life poker tournaments and play in the World Series of Poker Tournament.
So far there have been two recorded winners of the World Series of Poker Tournament who gained entry by playing Internet online poker.
Chris Moneymaker (2003) won the main event and caused a sensation within the poker world.
Then another Internet online poker player, Greg "Fossilman" Raymer, followed Chris' footsteps when he won the next year's World Series of Poker.
It's great that by playing poker online, you can earn money and have a chance at making it to the real-life poker tournaments.
But all of this is not without a sacrifice.
You will be asked to make an investment, especially for the Internet online poker tournaments where an entry fee and built-in fee is required.
You can also get hooked on so much Internet online poker that real things in your life are beings to suffer like relationships and career.
Remember, playing poker online is fun but don't let it run your life.
