The same way you measure everything else about broadcast - you find the people and ask them, aka "surveys".

- chrisseaton 6y agoAre AM listeners and FM listeners likely to find and respond to surveys in the same way? I would expect older more remote AM listeners would be under-represented in your survey.
- vertex-four 6y agoThere's a number of ways to try and avoid response bias - the most obvious would be to (a) work out roughly how many people are listening to AM radio at all, (b) go find some representative sample of people who are listening to AM radio and ask them what they're listening to, (c) scale your results proportionately. Nielsen specialises in this sort of research.
