Primary research is completely based on gathering your own data, so if you are wanting/needing to gather primary data, a questionnaire can be a useful way of collecting this information. For a questionnaire, you can design the actual thing yourself and then hand it out/put it online, because you will have created it yourself this allows you to really collect the information you need for your specific area. These can be used for when you need feedback on a particular media product, or if you also need to understand your target audience better.
Here is an example questionnaire I found on google after conducting a search 'questionnaires on media products' I found this in images, this is a girls questionnaire she needed to conduct for college work so it is a perfect example of how primary research can be collected.
