The organizational structure o f the specific sales department you'll work in is difficult to predict. The number o f employees and the support level o f any sales department is influenced by market size and by the vol­ ume o f sales dollars that the organization generates. For instance, you'll find that some large-market television stations have a director o f sales, a general sales manager, a local sales manager, a national sales man­ ager, a retail sales manager, a co-op manag­ er or coordinator, a research director, a sales staff o f 15 or more employees, an army o f sales assistants, and a traffic director.
