Why do large e-commerce companies choose the book industry?

The entry point of each e-commerce is different. The earliest e-commerce companies were based on books, and Dangdang and Zhuoyue should be the earliest. They entered the book e-commerce company in the 1990s, when the foot of my bed was still shining. . Why do they use books as a starting point? The social development conditions at that time, this may be the most operable. In the 1990s, you bought a 3C number online? Is it possible? How about buying a home appliance? Social trust has not been established. Do you dare to buy cosmetics and TV air conditioners? Large consumption is unrealistic, and the consumption level has not been established. Even if you buy it, logistics will not work. In case there is any after-sale, where is it broken, go to the door to repair it. . Merchants are too painful. Is it appropriate for you to buy a dress and shoes? At that time, logistics was underdeveloped, and it would take many days to take logistics. . In case you get it, the color and style will not look good. The comprehensive area of the lake does not match. Please return it in a few days, dear. Moreover, the book is a good, standardized product with low unit price and almost no after-sales problems. Then they went on doing it. There is another reason. There are many book resources in Li Guoqing, and they already exist. Just do it when you come up. You don't even have to accumulate supplier resources, which is much easier.
