Integrated marketing communication is an approach to achieving marketing campaign objectives through the coordinated use of different promotional methods that are intended to reinforce each other. It arose due to limitations in traditional advertising like low accountability and limited internet access. IMC involves inside-out, outside-in, and cross-functional strategic approaches. The inside-out approach focuses on a company's strengths and customers while the outside-in approach matches products to customer needs through research. The cross-functional approach restructures companies to be customer-centric and improve information sharing across departments.
