In our Internet-driven age, the balance of power for today's businesses has shifted.The consumer is now in control. In a world of consumer-generated media, or CGM (a term Pete Blackshaw coined),with ubiquitous blogs, video-sharing, and social networking, a single disgruntled customer can broadcast his or her opinions to millions and derail a multibillion-dollar company or undermine a global brand.Today, businesses can't afford to ignore CGM,and they no longer have anywhere to hide. The only way companies can respond, argues marketing and customer-loyalty expert Pete Blackshaw, is by creating 100 percent credibility with consumers on every front.
