The traditional role of design has been to improve the visual appearance and function of messages and information. The publishing industry relies on designers for printed and online books, magazines, and newspapers that inform, delight, and support the interests of readers. Designers distinguish businesses from their competitors in the marketplace through innovative approaches to branding, the comprehensive design of messages, products, and services that express the character of a company and define its relationships with consumers. Advertising design promotes the marketable qualities of commercial products and services through a variety of communication media. And information designers translate complicated numerical and textual explanations into visual forms that help people see patterns in data and relationships among the components of complicated ideas. In all these practices, designers use typography, photographs, illustrations, and graphic elements to construct messages that attract attention, cause us to think about their meaning, and stay in our memories over time.
