Algorithms are shaping the paradigm revolution of communication technology and causing the rise of new forms of communication, resulting in a new media ecology. The most prominent change is the expansion of the communication subject from humans to algorithms as “technical objects”. By tracing the sources of mass communication and community communication, we can see the context of why algorithmbased communication has become a new type of communication. Based on this, the process of the rise of algorithmic communication is analyzed. Algorithm-based communication has a shaping effect on social culture, which is embodied in the following: Algorithm-based communication is gradually deepening scene adaptation, reshaping people's cognitive and behavior patterns, and constructing new social relationships.
