Marketing isn't about using one medium. It's about getting and keeping customers. Yes, Internet marketing can help you can do that but only if you use it in conjunction with other tactical tools. In addition there are thousands of potential customers that are extremely cautious about placing important business or buying an expensive item from an unknown online vendor. That's one of the reasons why, in order to succeed, EVERY online company must have brochures and other forms of printed sales literature to hand out to customers and prospects.
