This week’s episode of “Empire” is currently at a new low for the Fox music drama in both key ratings measures, according to Nielsen overnight data.

Airing at 8 p.m., “Empire” averaged a 1.8 rating in adults 18-49 and 5.5 million total viewers. While that is not down significantly from last week’s episode (2.0, 5.9 million), it is nevertheless below the previous series low set by episode 15 of Season 3 (1.9, 5.6 million). There is of course the possibility that the show will adjust up when the final numbers come in later today. “Empire” has also consistently shown significant lift in delayed viewing.

On CBS, “Survivor” (1.7, 8 million) was even, while “SEAL Team” (1.0, 7 million) was down in both measures. “Criminal Minds” (1.1, 5.91) was even.

For The CW, “Riverdale” (0.6, 1.8 million) was down in both measures from last week’s season premiere. “Dynasty” (0.3, 0.98 million) held steady in the demo but dropped in total viewers.
