If something is important to me then I will hear it outside of the news. My neighbours, family, friends, email from government etc.
Of course, they might hear it from the news, but the idea is that I (and them) don't need to, to get on with life and still hear the important affective announcements.
The news is new.
It's more entertainment and sensation than information.
I do hear the news on the radio sometimes, this is ad supported and license fee supported. It's a side effect of listening to other programmes.
