That is very superficial research. Actually, folks who listen to the station that has Seacrest or Bobby Bones or whoever has a good morning show get news as part of the program.While the latter is true, I can guarantee you news radio is largely not one of the multiple mediums for the bulk of people under 50.
But news is not why they came to the show (I was gonna' say "tuned in" but that is pretty dated!). They came for the host of the show and the whole package. And on most stations, at least hourly news is part of that. But when asked, they say "I love Scott Shannon" or whatever. They don't say, "Oh, the show is OK but they really have terrific newscasts".
Radio is not used like Huffington Post or Breitbart.... morning shows are not driven by news. They are based on the talent(s) and, to some extent, the music. Not the news, so they don't mention that. But deep research reveals that news is one of the key ingredients.
Just like nobody goes to McDonalds and says "give me the two patty hamburger with the special sauce". They ask for a Big Mac. They order it by name because they like the "package". But if they get a Big Mac without the sauce, they will be storming the counter asking for a replacement!
