I am in the field of both education and marketing (I teach both education and marketing courses) and I have long said there is very little difference. In both, there is needs assessment and plans of action based on the context along with different ways to communicate the same message. Just like in education/training, however, there are differences in opinion as to the most "cost effective" way to meet goals (or sales targets).

In fact, there is a debate going on in the marketing world as to whether the new targeted marketing using new technologies is the way to go. "Viral Marketing" using things such as facebook has really taken off. But more traditional organizations have criticized this form of marketing as it is difficult to measure its impact (sound familiar on the training side?). I think, like marketing, there will always be the traditionalists, but they will start to change as there is evidence of the impact that training 2.0 (for lack of a better term) has on organizational learning and acheivement.
