Word-of-mouth marketing is any initiative that prompts customers to talk to other people about a product or service. There are several breeds.
Promoting products or services through messages and video spread by consumers via e-mail.
Winning attention for products by putting them in the hands of celebrities.
Targeting the connected or cool people that lemmings will most likely follow.
Marketing disguised as something else. Word-of-mouthers consider this their evil twin. Anyone who thinks ill of word of mouth, they contend, is probably confusing it with this.
