Here is the definition of a Marketing Stream.

Marketing Stream – A series of planned marketing and sales events that bring in customers to a business in order to make a sale. After the sale, another series of planned marketing and sales events are continuously applied in order to facilitate them becoming repeat customer for life. Once a customer enters the Marketing Stream they are then called a Continual Customer.

This differs from a Marketing Funnel.  In a Marketing Funnel, the primary goal is to get the customer to buy something and that is pretty much about it.

A Marketing Funnel is to a single fishing pole as a Marketing Stream is compared to a net.

The net is going to get a lot more fish or customers and ultimately profits.
