This document discusses different types of market testing for new products. It describes market testing as experimentally marketing a product at minimum cost and risk in selected market segments. The main types of market testing discussed are sales wave research, simulated test marketing, controlled test marketing, and test markets. Sales wave research involves providing the new product to customers for free multiple times to evaluate repeat purchases. Simulated test marketing uses mathematical models to estimate market share based on initial consumer reactions. Controlled test marketing manages specific stores that carry the product for research purposes. Test markets involve specifically choosing representative cities to test sell the product and gather feedback.
