Integrated marketing communications (IMC) is an approach that sees marketing from the customer's perspective. IMC involves evaluating the strategic roles of various communication disciplines like advertising, direct marketing, public relations, and sales promotion, and combining them to maximize impact. It provides a more coordinated approach compared to relying primarily on advertising. IMC has grown due to factors like a shift in power from manufacturers to retailers and the rise of new technologies. The promotional mix refers to the optimal combination of advertising, sales promotion, public relations, personal selling, and direct marketing used in an IMC strategy.
