The Story of Sears

Once there was a company called Sears. You could use a book, or "catalog" Sears published to select items to purchase. Then you could mail your order with a check or money order to Sears, and your package would be delivered to your house.
Eventually, Sears relied on (brick and mortar) stores that people came to, to buy things.
Then when everyone was shopping on the Internet, a company called Amazon had items for sale on their website. Customers could select what they wanted to buy and pay with a credit card. Then the package would be delivered to their house.
This new idea for selling things eventually put Sears out of business...
