The document describes an IBM case study where traditional sales approaches like telemarketing and email were not effective for selling web-based services like cloud computing and data security. IBM implemented a strategy of having sales representatives intelligently listen in social media groups to understand customer needs and problems. The reps participated in discussions and edited social media posts to sound authentic. This low-cost approach helped the reps gain 3,000 new LinkedIn followers, expanding their potential reach from 54,000 to 1.3 million and boosting engagement and sales.
