Before the 1990 s, the Internet was in the early stage of development.In this period, many scholars have explored the Internet, for example, the Internet father of the Internet, and Bob Kahn, created the TCP/ IP communication protocol; the first domain name of the world in 1985 was born; the first search engine in the world was born in 1990 and so on.

In the 1990s, Internet portals rose.In 1994, the famous Internet portal Yahoo was established in the United States. Then around 1998, four Chinese portals represented by Sina, Sohu, Netease and Tencent were established one after another.

At the beginning of the new century, the Internet is no longer limited to the transmission of information, but more social, entertainment and consumer attributes.Companies such as Twitter and Amazon in the United States have risen, while China has risen rapidly from Renren, Kaixin to BAT (Baidu, Ali and Tencent).

In the era of mobile Internet, people's life is more and more convenient.

Since 2010, with the continuous breakthrough of cloud computing, big data, artificial intelligence, virtual reality, 5G and other technologies, the Internet has gradually developed from a network model all over the world to a brain model that combines human intelligence with machine intelligence.Today, almost all Internet giants have launched "brain" systems, Google brain, Baidu brain, iFLYTEK superbrain, Ali ET brain, Tencent super brain, Didi traffic brain, 360 safe brain andHUAWEIBrain systems such as EI agents have sprung up.
