ACSI measures customer satisfaction with the products and services of approximately 200 companies in 43 household consumer industries and nearly 100 major customer segments of federal agencies. Within each industry companies are selected on the basis of total sales and the measured companies represent a significant proportion of the overall market share of the industry. Individual companies are added or deleted from ACSI as their market position changes or as a result of mergers and acquisitions. Industries are added as new types of consumer products or services emerge and grow over time like Internet retailers or wireless telephone service carriers.
