The first wave was the portal website ten years ago, which reorganized the Internet by manual editing. At that time, their contents were all from various print media. Although many websites provide various contents at this time, the websites we can remember are Sina Sohu and so on. Now our most commonly used website is search, and now they have succeeded. This is the second wave. In the early days of portal websites, including the current search, few original content was provided. Therefore, the integration of Internet content has become the integration of the third wave.
So the first time is the portal, the second time is the search engine, and the third time is the integration of Internet content.
