Market Research is all about exploring what consumers want, how they think, why they buy some products and not others, and how they shop. Each year corporations in the U.S. alone spend billions of dollars trying to learn this information. They use stuff like compensated surveys, focus groups, clinical trials, get paid to drive studies, mystery shopping studies, product testing, and other means to gather this information. This information is absolutely vital to the success of companies as it gives companies the ability to quickly create and/or improve existing products and it also prevents them from developing useless products.  Market Research is an ongoing expense for businesses and an ongoing opportunity for participants to earn compensation.
