First of all, the concept of all-media
In recent years, there is no unified definition of the concept and connotation of all-media in academic circles. On the basis of research and preliminary practice, it is found that scholars in the past mainly defined the concept of all-media from two aspects: on the one hand, from the perspective of brand-new media operation mode, on the other hand, from the perspective of new media communication form. From a macro point of view, the real connotation of all-media is a brand-new information production mode and communication concept. At the micro level, it can be analyzed from the following points. From the perspective of communication form, we can simply summarize the whole media as the sum of many single media; Judging from the content of communication, the whole media covers multi-dimensional information such as text, pictures, sound, light and electricity. From the perspective of information media, it includes traditional media, new media and emerging media based on the Internet. "In the practice of the media industry, any form of media practice that combines different media is called all-media. [1] "Therefore, all-media is a concept developed with the continuous development of information technology and network technology.
Second, the change of advertising communication in the all-media era.
When people enjoy the unprecedented benefits of information integration, convenience and personalization brought by all media; When advertising companies adjust their strategies for the new integration direction of the media industry; When advertisers use all the advantages of all media to expand the effect of information dissemination, they soon find that the all-media era has brought people a double-edged sword. Diversified media selection has brought further fragmentation of advertising audience, thus diluting the communication effect of single media; Diversified data terminals have changed the traditional relationship between transmission and reception, thus expanding the functional vision of advertising, which has aroused in-depth thinking in the advertising industry and academia. With the digital transformation of traditional media, the emergence of new media and the deepening of media integration, the connotation of all-media has penetrated deeper and deeper in the practice of advertising communication. In the all-media era, the advertising communication environment has changed greatly compared with before, and the change of advertising communication environment has brought about the evolution of multi-angle relationship in advertising industry.
