The Internet has become a virtual world. There is nothing that you can do in the real world that you cannot do in the virtual world including buying and selling products. This has been a known fact for some time, and when you promote products on the net it is called Internet marketing. There are a number of websites that sell products and a few large organizations that dominate the market. Companies like Amazon and eBay are some of the most commonly known names although there are a few others as well. While Amazon and eBay sell products, they do not actively advertise for them. Considering their sales volume and growth – Amazon grew 16% last year when compared to 2.4% for retail sales, it is possible that they feel that they do not need to advertise. Yet everyone knows the value of advertising.
