Although there are many chronological views of the history of marketing, there are really only three core conceptual views of marketing that have been dominant in our lifetimes: Push, Pull and Collaborative.
In the beginning, there was push marketing. Historically, almost all of us have been taught a push method of marketing. We provided a value proposition, pitch or sample in one of a limited set of channels for consumption.
Marketing was mainly differentiated by the creative quality or educational value of the marketing approach, but it was notoriously difficult to calculate the value of marketing efforts. In effect, it was a Mad Men shotgun approach: shoot a bunch of pellets vaguely in the direction of a target and hope that your creative efforts hit a target.
