I've seen that claim too and found it questionable. Almost every major news outlet that would cover international news I found had some story about coronavirus pretty dang early. It wasn't a breathless story predicting the impact, but they covered it.
I feel like most media "media does this" or "didn't do that" is mostly just what passed in front of someone's nose.
Purely anecdotal experience of mine was a reddit story ages ago that was "The Media is too busy covering X to cover this story Y."
Purely out of curiosity I turned around and flipped on the TV and checked the news channels. The first 3 news channels, 2 were covering Y... but the claims about nobody covering it were constant.
