Abstract
This contribution reviews the vast scope of digital application areas, which shape the digital marketing landscape and coin the present term "marketing intelligence" from a marketing technique point of view. Additionally, marketing intelligence as social engineering techniques are described. The review ranges from digital IT- and big data marketing until marketing 5.0 as digitalized trust marketing. The multiplicity of applications and interdependencies of the digital and social techniques reviewed should show that big data and marketing intelligence have already become a marketing reality. It becomes clear that marketing is witnessing a methodological, technical and cultural paradigm shift that augments and amplifes traditional outbound marketing with inbound marketing.
