According to E. Toffler's concept, presented in his book "The Third Wave" in 1980, a prosumer is both producer and consumer. Prosumers are characterized by a Do It Yourself (DIY) approach based on manual work and use of electronic and household appliances in order to improve and modernize consumed economic goods. In many ways, the do it yourself trend is based on subcultural and underground practices of the second half of the 20th century.
The new cybernetic reality Web 2.0, described by Tim O'Reilly in 2005 in his article "What Is Web 2.0", created a new type of prosumer, which tends to engage in mental activity and, based on new information technologies, solve some of the problems associated, for example, with improvement of projects and services created in the network.
The principles of prosumption and maker culture are available, they have a low entry threshold : they do not require participation of large governmental or economic structures to be implemented. Initiative of the Kruzhok or workshop members, individuals and groups is enough. Thanks to proactive attitude, a person becomes more than just a consumer susceptible to manipulation. He\she takes responsibility for his\her life, affects the environment and interfaces they interact with directly.
