This study sorts out the media development and trends in China in 2019，analyzes and interprets emerging tendency of media channels，e.g. online media，TV，radio，OOH，newspaper，magazine and so on；meanwhile，it also makes deep analysis on lifestyle transformation of Chinese residents in 2019 on the basis of data comparison. This study finds that the end of Internet traffic dividend has led to a new stage of communication and consumption. Firstly，the growth rate of Internet media slows down and tends to be saturated. The sinking market becomes the blue ocean market of Internet competition，and the traffic continues to permeate the middle-aged and senior citizens. Secondly，with the increase of the penetration rate of short video among all Internet users，the explosion of short video industry has become the most significant feature of the development of Internet media in the past two years. In terms of traditional media，the decline of daily arrival rate of TV is slowing down，and TV still has higher authority than other media，and it is still the media most recognized by residents. broadcast media has bucked the trend and developed steadily，and with the rapid development of Internet audio，the “ear economy” has emerged. Thirdly，in the outdoor travel scene，OOH has a strong momentum of development and enters the fast lane of digital transformation. Fourthly，print media is experiencing a tremendous transformation towards mobility，digitalization and intelligence. The change of residents’ lifestyle is also deeply influenced by the development trend of the Internet. The saturation of traffic and the gradual loss of dividend bring the new consumption characteristics，which promote the consumption to be more differentiated. The consumption of “Generation Z”，silver consumption，“Her” economy and maternal and infant consumption become new market growth points. It is an important prerequisite for media marketing and consumer marketing to understand the latest trends of media and consumer lifestyle in China.
