The reason is simple. If you have kept in touch with the current news, you would have notice that there is an increasing trend in online shopping including digital products like E-Books.
This creates a very large market for products to be sold and we are talking about a world wide market.
So ask yourself now. Why do you target only the audiences in your country when you can actually showcase your product to the whole world.
6 million population vs the entire world of at least 6 billion. The thought of this excites me and make me decide to go on with internet business.
1) Low or almost no start up cost. ( Needed only to purchase domain names and site hosting )
2) No need for inventory. ( Affliate marketing which is selling other's product )
3) Low Risk
With all this in mind, it makes internet business very lucrative and I will begin with it.
