In 1998 consumers could purchase virtually anything over the Internet. Books, compact discs, and even stocks were available from World Wide Web Sites that seemed to spring up almost daily. A few years earlier, some people had predicted that consumers accustomed to shopping in stores would be reluctant to buy things that they could not see or touch in person. For a growing number of time-starved consumers, however, shopping from their home computer was proving to be a convenient alternative to driving to the store. A research estimated that in 1998 US consumers would purchase $7.3 billion of goods over the Internet, double the 1997 total. Finding a bargain was getting easier, owing to the rise of online auctions and Web sites that did comparison shopping on the Internet for the best deal. For all the consumers’’ interest, retailing in cyberspace was still a largely unprofitable business, however. Internet pioneer Amazon.com, which began selling books in 1995 and later branched into recorded music and videos, posted revenue of $153.7 million in the third quarter, up from $37.9 million in the same period of 1997. Overall, however, the company’’ s loss widened to $45.2 million from $9.6 million, and analysts did not expect the company to mm a profit until 2001. Despite the great loss, Amazon.com had a stock market value of many billions, reflecting investors’’ optimism about the future of the industry. Internet retailing appealed to investors because it provided an efficient means for reaching millions of consumers without having the cost of operating conventional stores with their armies of salespeople. Selling online carded its own risks, however. With so many companies competing for consumers’’ attention, price competition was intense and profit margins were thin or nonexistent. One video retailer sold the hit movie Titanic for $9.99, undercutting(削价) the $19.99 suggested retail price and losing about $6 on each copy sold With Internet retailing still in its initial stage, companies seemed willing to absorb such losses in an attempt to establish a dominant market position.
A.Consumers are reluctant to buy things on the Internet.B.Consumers are too busy to buy things on the Internet.C.More and more consumers prefer Internet shopping.D.Internet retailing is a profitable business.
