The Scooby Doo episode of “Supernatural” provided the long-running CW series with its best ratings since the Season 13 premiere back in October in the Nielsen overnight ratings. Airing at 8 p.m., “Supernatural” drew a 0.7 rating in adults 18-49 and 2 million viewers. That is an increase of over 30% in the demo and approximately 20% in total viewers over the last original episode of the show.

The lift did not translate to fellow CW show “Arrow,” however, which was down slightly from last week with a 0.4 and 1.1 million viewers.

CBS’ Thursday lineup was mostly steady, with only “Life in Pieces” seeing a slight decline week-to-week in the demo. “Big Bang Theory” averaged a 2.4 and 12.9 million viewers, making it the top show of the night in both measures. “Young Sheldon” drew a 2.0 and 11.7 million viewers. “Mom” drew a 1.4 and 8.7 million. “Life in Pieces” is at a 1.0 -and 6.2 million. “SWAT” drew a 0.9 and 5.3 million.

For ABC, “Grey’s Anatomy” (1.7, 6.99 million) was down slightly in the demo. “Station 19” (1.2, 5.8 million) improved slightly from its premiere last week. “Scandal” (0.8, 3.8 million) took serious hits in both measures in its later timeslot.
