MATURITY STAGE: The third stage in the product life cycle, characterized by flattening of sales and decreasing profit margins. Advertising and promotion are used to maintain market share and to prevent the erosion of sales and profits. During this stage, the initial decline of a product begins and many businesses try to "re-invent" their products to prevent the upcoming decline stage. Many times the company finds new uses for an existing product (baking soda as a deodorizer), totally new markets (foreign countries), or a way to enhance the existing product to make it better and to re-start the life cycle. The television has gone through at least two life cycles, first from black and white to color and then from color to high definition (HD) and plasma. Along the way there were enhancements such as remote control, VCRs to complement them, and cable to help with reception.

CONCENTRATION RATIOS

A family of measures of the proportion of total output in an industry that is produced by a given number of the largest firms in the industry. The two most common concentration ratios are for the four largest firms and the eight largest firms. The four-firm concentration ratio is the proportion of total output produced by the four largest firms in the industry and the eight-firm concentration ratio is proportion of total output produced by the eight largest firms in the industry. Concentration ratios are commonly used to indicate the degree to which an industry is oligopolistic and the extent of market control of the largest firms in the industry. A related measure is the Herfindahl index.

Be on the lookout for bottles of barbeque sauce that act TOO innocent.
