Word of Mouth marketing at Procter & Gamble

Great story in last week’s Business Week about word-of-mouth strategies at Procter & Gamble, which already in test markets has doubled sales of certain products. The story is worth a read for anyone engaged in or interested in word-of-mouth marketing as a legitimate, significant and measurable arm of your marketing strategy. This could very well be the most influential and powerful marketing channel available to marketers in ten years.
