Traditional marketing channels such as print, radio, and even digital marketing rely on “short-burst” communication.  The customer is only engaged for short periods,  and the impact is short-lived. Podcasting fully engages the listener for 20, 30, 40 minutes or more, offering a fuller and longer-lasting exposure to your brand.
Secondly,  the customer interaction taking place in traditional marketing vehicles tends to be transactional.  The delivered messages are limited in scope and do little to make an impact on the customer’s life. Truly effective podcasts are designed to be important to the customers’ personal and/or professional development and be a source of entertainment. As a result, your relationship with your customer becomes more "sticky", and your brand becomes important to them.
