"come up with"

And I'm afraid your credibility isn't the best, after you made an authoritative statement which, it turned out, did not come from your own experience, but rather "reliable reports".   I thought, with your handle, that you had in fact experienced this yourself.

It's not likely the racist flood was "calculated".   The US government does not control the media, even if you have paranoid suspicions along those lines.

And the networks would not be helped by a "racist flood" after the broadcast--what they want is high ratings during the broadcast.

So your parallel has serious flaws.
