According to the Department of Labor's Occupational Outlook Handbook:
Advertising, marketing, promotions, public relations, and sales managers coordinate their companies’ market research, marketing strategy, sales, advertising, promotion, pricing, product development, and public relations activities. In small firms, the owner or chief executive officer might assume all advertising, promotions, marketing, sales, and public relations responsibilities. In large firms, which may offer numerous products and services nationally or even worldwide, an executive vice president directs overall advertising, marketing, promotions, sales, and public relations policies. (Executive vice presidents are included in the Handbook statement on top executives.)
Advertising managers. Advertising managers oversee advertising and promotion staffs, which usually are small, except in the largest firms. In a small firm, managers may serve as liaisons between the firm and the advertising or promotion agency to which many advertising or promotional functions are contracted out. In larger firms, advertising managers oversee in-house account, creative, and media services departments. The account executive manages the account services department, assesses the need for advertising and, in advertising agencies, maintains the accounts of clients. The creative services department develops the subject matter and presentation of advertising. The creative director oversees the copy chief, art director, and associated staff. The media director oversees planning groups that select the communication media—for example, radio, television, newspapers, magazines, the Internet, or outdoor signs—to disseminate the advertising.
Marketing managers. Marketing managers develop the firm’s marketing strategy in detail. With the help of subordinates, including product development managers and market research managers, they estimate the demand for products and services offered by the firm and its competitors. In addition, they identify potential markets—for example, business firms, wholesalers, retailers, government, or the general public. Marketing managers develop pricing strategy to help firms maximize profits and market share while ensuring that the firm’s customers are satisfied. In collaboration with sales, product development, and other managers, they monitor trends that indicate the need for new products and services, and they oversee product development. Marketing managers work with advertising and promotion managers to promote the firm’s products and services and to attract potential users.
Promotions managers. Promotions managers supervise staffs of promotions specialists. These managers direct promotions programs that combine advertising with purchase incentives to increase sales. In an effort to establish closer contact with purchasers—dealers, distributors, or consumers—promotions programs may use direct mail, telemarketing, television or radio advertising, catalogs, exhibits, inserts in newspapers, Internet advertisements or Web sites, in-store displays or product endorsements, and special events. Purchasing incentives may include discounts, samples, gifts, rebates, coupons, sweepstakes, and contests.
Public relations managers. Public relations managers supervise public relations specialists. (See the Handbook statement on public relations specialists.) These managers direct publicity programs to a targeted audience. They often specialize in a specific area, such as crisis management, or in a specific industry, such as health care. They use every available communication medium to maintain the support of the specific group upon whom their organization’s success depends, such as consumers, stockholders, or the general public. For example, public relations managers may clarify or justify the firm’s point of view on health or environmental issues to community or special-interest groups.
Public relations managers also evaluate advertising and promotions programs for compatibility with public relations efforts and serve as the eyes and ears of top management. They observe social, economic, and political trends that might ultimately affect the firm, and they make recommendations to enhance the firm’s image on the basis of those trends.
Public relations managers may confer with labor relations managers to produce internal company communications—such as newsletters about employee-management relations—and with financial managers to produce company reports. They assist company executives in drafting speeches, arranging interviews, and maintaining other forms of public contact; oversee company archives; and respond to requests for information. In addition, some of these managers handle special events, such as the sponsorship of races, parties introducing new products, or other activities that the firm supports in order to gain public attention through the press without advertising directly.
