One-to-many communication is mass communication in which information is transmitted from a central point to many participants. In classic technology, radio and television are typical one-to-many transmissions. On the Internet, it is websites that occupy the central position of information distribution.
Since in classical one-to-many communication there was no back channel, the information provider could not draw any conclusions about the information content. He had no information from the participants on the content and its presentation and could not answer questions from participants. It was not until the advent of social networks that services were created that enabled individualized communication from an individual to an individual within a group and that also allowed feedback. Blogs and microblogs are among the services, the best known of which is Twitter.
