     In the mid 1990's, people started doing business on the Internet. At that time, there were two kinds of

companies. First, there were traditional companies which sold things in stores. Then, there were Internet

companies which didn't have stores; they sold things only over the Net.

     Traditional companies didn't want to lose any business. Quickly, they created their own websites and

began selling things over the Net. These are the so-called "brick and click" companies. Many stores are

made of brick, and you click on your mouse to buy things with your computer. That's where the name

"brick and click" comes from.

     By the late 1990's, e-businesses like Amazon.com, Buy.com, and eToys.com were in trouble. Their

profits were not very high, and there was a lot of competition. Many of these businesses lost a lot of money,

and in 2000, many businesses were out of business. Why are brick and click companies, like Barnes and

Noble, Toys RUs, and Walmart 50 successful? First, many customers know and trust their names. Their

websites, like Walmart.com, are easy to remember. These companies also have a lot of experience. They

know how to run a successful business.

     In the world of e-commerce (电子商务), companies are fighting for every dollar and every customer.
