ABSTRACT
In marketing sales quotas and plans, advertising campaigns, and budgets are all factors that are significantly affected by seasonal patterns. The term 'derived demand' is usually applied to the industrial goods market. Commodities used for industrial rather than household purposes are said to exhibit derived demand-that is, they depend for their very existence upon products sold to consumers. The difference between primary and selective demand is particularly important to the marketing function. The pharmaceutical market is not the only one characterized by periodic replacement of top-selling products by new entries. The non-barbiturate sedative market illustrates the effect of a dominating product innovation. Each stage of the life cycle of a particular type of product is characterized by differing market conditions and marketing activities. Conversely, the marketing activities of the firm affect the life cycle. In a modest study of firms characterized as successful and unsuccessful in terms of market.
