Panels are groups of respondents who have agreed to participate in research studies. They are not inexpensive to recruit and maintain, and they may not always deliver random samples. Additionally, if the panel is overworked, respondents may become fatigued or lose interest, which can impact the quality of their responses. Focus groups and social media research participants may also have some of these issues, but they are not typically referred to as being overworked. Media research participants may be drawn from panels or other sources, but the question specifically asks about participants recruited by media research companies, which is a more limited group.
