The invention relates to a live broadcasting method, device and system, and belongs to the technical field of communication. The live broadcasting method, device and system are applied to an anchor client. The live broadcasting method comprises the steps of obtaining live broadcasting information stream sent by a microphone connection client in a live broadcasting process, wherein the microphone connection client is a client which carries out microphone connection live broadcasting, together with the anchor client; detecting target behavior information in the live broadcasting information stream; in response to the detected target behavior information, determining a target virtual present which corresponds to the target behavior information; and carrying out a present-giving operation, wherein the present-giving operation gives an instruction to give the target virtual present to a microphone connection live broadcaster which corresponds to the microphone connection client. The live broadcasting method solves the problem of a relatively single interaction mode of the anchor client and the microphone connection client, and enriches the interaction mode. The live broadcasting method is used for live broadcasting.
