What is 'supply and demand'?

Promotion involves disseminating information about a product, product line, brand, or company. It is one of the four key aspects of the marketing mix. (The other three elements are product marketing, pricing, and distribution.) Promotion is generally sub-divided into two parts: Above the line promotion: Promotion in the media (e.g. TV, radio, newspapers, Internet and Mobile Phones) in which the advertiser pays an advertising agency to place the ad Below the line promotion: All other promotion. Much of this is intended to be subtle enough for the consumer to be unaware that promotion is taking place. E.g. sponsorship, product placement, endorsements, sales promotion, merchandising, direct mail, personal selling, public relations, trade shows The specification of these four variables creates a promotional mix or promotional plan. A promotional mix specifies how much attention to pay to each of the four subcategories, and how much money to budget for each. A promotional plan can have a wide range of objectives, including: sales increases, new product acceptance, creation of brand equity, positioning, competitive retaliations, or creation of a corporate image. The term "promotion" is usually an "in" expression used internally by the marketing company, but not normally to the public or the market - phrases like "special offer" are more common. An example of a fully integrated, long-term, large-scale promotion are My Coke Rewards and Pepsi Stuff.
