Many companies today spend a small fortune on marketing and advertising efforts. Everyone from clothing manufacturers to breakfast cereal companies want to know what your preferences are as a consumer, and they want to know what it is about their products that you like or dislike. When you complete online surveys, you are giving these companies valuable feedback, and they use your input as well as the input of hundreds or thousands of others to improve their marketing efforts and develop new products. In addition, even TV and movie production companies use paid surveys to learn about your entertainment preferences and interests.
