Which of the following is an example of first party research that can aid in developing a media strategy?

First-party research is data collected directly by a company from its own customers or audience, which can provide valuable insights for developing a tailored media strategy. Focus groups are a type of first-party research where a selected group of individuals discusses their thoughts and feelings about a product, service, or concept. This qualitative approach allows for deep insights into consumer attitudes, preferences, and motivations, making it a powerful tool for media strategists seeking to understand their target audience's perceptions and reactions.

Surveys, while also a method of gathering first-party data, can be quantitative in nature and may not always provide the nuanced understanding that focus groups offer. Industry reviews and market trends, on the other hand, are typically based on secondary research and external data sources rather than direct insights from a company's own customer base, which means they do not fall under the category of first-party research.
