2020 is a memorable year. We have experienced the epidemic together. In this extraordinary year，the Internet broadcasting industry has also experienced extraordinary things. In 2020，with the birth of the first listed company in the network broadcasting industry，the whole industry has entered the middle and late stage of investment，and various platforms have approached the pre IPO stage. With the application of 5G，the application of aiot has gradually become possible，opening a new growth point for the network broadcasting industry. Each network broadcasting platform has gradually formed a solid foundation of four mature profit models，and began to actively explore the layout of aiot in the field of smart home and smart car. Even there are more exploratory network broadcasting platforms，which actively layout the ecology of Internet of things. Based on the steady growth of the whole network broadcasting industry in 2020，a new stage of network broadcasting industry has arrived. We are looking forward to 2021.
