Yes, that would be different. In your instance the data is a non random sample. Non randomly sampled data will always be skewed, i.e., contaminated.
My concern was the small sample size of only 400 people. The margin of error (plus or minus) is fairly large with a sample size that small to be able to say that other forms of media are NOT putting a dent into radio listenership.

Maybe, or maybe not, but that survey is not much to go on either way.
