How does integrated marketing communications unify promotion?

"Ideally, marketing communications from each promotional-mix element—personal selling, traditional advertising, sales promotion, public relations, social media, and e-commerce—should be integrated. That is, the message reaching the consumer should be the same regardless of whether it comes from an advertisement, a salesperson in the field, a magazine article, a blog, a Facebook posting, or a coupon in a newspaper insert.\n\nThis disjointed approach to promotion has propelled many companies to adopt the concept of integrated marketing communications (IMC). IMC involves carefully coordinating all promotional activities—traditional advertising, including direct marketing, sales promotion, personal selling, public relations, social media and e-commerce, packaging, and other forms of promotion—to produce a consistent, unified message that is customer focused. Following the concept of IMC, marketing managers carefully work out the roles the various promotional elements will play in the marketing mix. Timing of promotional activities is coordinated, and the results of each campaign are carefully monitored to improve future use of the promotional mix tools. Typically, a company appoints a marketing communications director who has overall responsibility for integrating the company’s marketing communications.\n\nWhen Weight Watchers signed up DJ Khaled to be one of its celebrity endorsers, many were surprised by the choice. Khaled will broadcast his quest to slim down across Facebook, Instagram, Twitter, and Snapchat in a bid to attract more men to sign up for the program. Khaled is not the usual choice for a Weight Watchers spokesperson, but once you scratch below the surface, he’s actually a great brand fit. Authenticity and relevance are words bandied about like the gospel in influencer marketing, but they are the most important ingredients when it comes to working with any level of influencer."
