Marknaden för influencers omsätter nu 650 miljoner

Influencer marketing (also influence marketing) is a form of marketing in which focus is placed on influential people rather than the target market as a whole. It identifies the individuals that have influence over potential buyers, and orients marketing activities around these influencers. Influencer content may be framed as testimonial advertising where they play the role of a potential buyer themselves, or they may be third parties. These third parties exist either in the supply chain (retailers, manufacturers, etc.) or may be so-called value-added influencers (such as journalists, academics, industry analysts, professional advisers, and so on). The idea of a "two-step flow of communication" was introduced in The People's Choice (Paul Lazarsfeld, Bernard Berelson, and Hazel Gaudet, a 1940 study on the decision making process of voters). This idea was further developed in "Personal Influence" (Lazarsfeld, Elihu Katz 1955) and "The Effects of Mass Communication" (Joseph Klapper 1960).
