What are the profit models of Internet businesses?

The first mode is the most traditional mode of selling goods, which can include traditional department stores and massage services. This model is realized on the Internet as e-commerce and O2O.\x0d\\x0d\ The second model is also considered to be selling "goods", but the goods are a bit special, selling the right to use digital products. The first is the Windows License model, and now it is reflected in the IaasS, PaaS, SassS service fees. Windows, Oracle is still the License model, but the cloud services have been excessive to only charge service fees. \x0d\\\x0d\\ Thirdly, there is the platform sharing model. This is more evident on sites like Starting Point, where authors share revenue from paid subscriptions with Starting Point. \x0d\\\x0d\\ The fourth model is the advertising model. This model is essentially the equivalent of selling traffic. And advertising itself can be divided into three generations: the first generation is the small ads on poles type, the ads on portals, the ads on TV are of this kind; the second generation is the Google type, which provides associated ads based on the keywords; and the third generation is based on the people, and the soft copy type of ads are of this kind. \x0d\\\x0d\\ The fifth type is selling value-added items. Games and QQ crowns are this model. \x0d\\\x0d\\ Sixth is the virtual central bank model. This one is more special and needs to be said a little more. The difference between a central bank and a normal bank is that it does not make money, but creates money. In reality a central bank can collect mint taxes by issuing more money, but for the virtual world this is a profit model. Imagine if a virtual community is big enough, then its virtual currency has a very high exchange value, so that the amount of issuance is the money that can be earned.
