The chapter begins by examining the spectacular evolution of marketing over the past seven decades, which has unfolded in parallel with the dynamics of the Internet. The stages from Marketing 1.0 to Marketing 6.0 have evolved alongside the transition of the Web from Web 1.0 to Web 6.0. The remarkable contribution of Professor Kotler is highlighted, both as a disseminator of fundamental marketing knowledge and as a visionary in the evolution of this scientific field. Illustrative diagrams related to Marketing 1.0 and the transformations that occurred with the shift to Mk 2.0 and Mk 3.0 facilitate a better understanding of Mk 4.0, which sets the stage for Mk 5.0 as a higher level of evolution in the field. Today’s marketing—Mk 6.0 is treated through its instruments and their objectives. Concrete references are made throughout all stages to illustrative examples from Romania’s marketing experience, which can also serve many other countries in the contemporary global economy.
