About ten years ago, we shopped only at local stores in the market place using cash. Now a new world has been opened up to people around the globe through the World Wide Web. We are able to browse the fanciest shops in the world from home, “virtually” that is. The technology of secure transactions on the Web has greatly improved and the rush to buy from online shops has demonstrated a growing consumer acceptance of online marketing. Increasingly, online marketing is no longer just an option. It is a necessity. Online marketing is an electronically-based industry. In short, it refers to the conducting of business through the Internet. It is a way of buying and selling goods and services, and negotiating trade through digital communications. Online marketing allows businesses to reach a wider market while cutting costs, saving time and eliminating tons of paperwork. Most online retailers ask the customers to pay with a credit card. Regular buyers are issued electronic or digital signatures which are protected by passwords, enabling them to transact business securely via Internet. Online marketing is still in its early stages, as problems such as how to deal with credit card fraud on the Internet still have to be dealt with. But its future looks rosy. With the development of computer technology, e-commerce will inevitably become a “must” in our everyday lives. There is no doubt e-commerce has come of age. 1. _ _ _ _ _ _ _ _ _ _ changed the way a company might carry out a marketing strategy over the past 10 years.回答ABC正确获得10.00分中的10.00分 A. The Internet B.
