The TV ratings surge, which seemingly can only be attributed to the coronavirus pandemic, continues, as a quartet of shows all drew season high viewerships in Thursday night.

On ABC, “Grey’s Anatomy” and its “Station 19” spinoff smashed their viewership records for the season, drawing 7.1 million and 7.5 million respectively.

NBC has an equally rosy night, with two of its comedies reaching new viewership heights. “Superstore” drew a season 5 high 3.8 million viewers (and a season high 0.9 rating), while “Will & Grace”‘s 2.8 million figure was also the largest for its final season so far (as was its 0.7 rating). “Brooklyn Nine-Nine” matched it season high rating with a 0.7 and 2.5 million viewers. “Indebted” delivered a freshman season high 0.5 and 1.9 million viewers, followed by an NBC News coronavirus pandemic special which led the night at a 0.9 and 4.2 million viewers.
