From the FCC itself (emphasis added):With all of the Fake News coming out of NBC and the Networks, at what point is it appropriate to challenge their License? Bad for country!— Donald J. Trump (@realDonaldTrump) October 11, 2017
We license only individual broadcast stations. We do not license TV or radio networks (such as CBS, NBC, ABC or Fox) or other organizations with which stations have relationships (such as PBS or NPR), except to the extent that those entities may also be station licensees. We also do not regulate information provided over the Internet, nor do we intervene in private disputes involving broadcast stations or their licensees. Instead, we usually defer to the parties, courts, or other agencies to resolve such disputes.But even if FCC does not license networks themselves, it can cause trouble for media companies. On September 15, 1972, Nixon talked about using it to punish The Washington Post.
PRESIDENT: The Post has asked -- it's going to have its problems.
DEAN: The networks, the networks are good with Maury [Maurice Stans]coming back three days in a row and --
PRESIDENT: That's right. Right. The main thing is the Post is going to have damnable, damnable problems out of this one. They have a television station.
DEAN: That's right, they do.
PRESIDENT: And they're going to have to get it renewed.
HALDEMAN: They've got a radio station, too.
PRESIDENT: Does that come up too? The point is, when does it come up?
DEAN: I don't know. But the practice of nonlicensees filing on top of licensees has certainly gotten more,...
PRESIDENT: That's right.
DEAN: more active in the, in the area.
PRESIDENT: And it's going to be God damn active here.
PRESIDENT: Well, the game has to be played awfully rough.
