Word of Mouth
No ad or salesperson can convince you about the virtues of a product
as persuasively as can a friend, acquaintance, past customer, or independent
expert. Suppose you are planning to buy a PDA (personal
digital assistant) and you have seen all the ads for Palm, HP, and
Sony. You even go to examine them at Circuit City and listen to the
salesperson. You’re still undecided and don’t buy. Then a friend tells
you how Palm has changed her life. That does it. Or you read a column
by an expert who tested and describes each one and recommends
Palm.
