Everyone in marketing, advertising, or public relations is involved in communicating with the public and helping to shape its opinions and perceptions. With the help of their subordinates, marketing managers research the demand for their company's products or services, develop pricing strategies, and identify likely customers.

They often work with advertising managers, who are usually employed by ad agencies. Advertising managers supervise the people who write and design ads, buy commercial time on TV, or deal with clients. Public relations managers are employed by both in-house corporate PR departments and by public relations agencies.

The pay is usually good. But long hours, including weekends and extensive travel are common. You'll have to work your way up, but as the economy becomes ever more global and competitive, there will be a growing need for managers who can communicate effectively to the public.
