Ratings: Arrowverse Crossover Opener Lifts Supergirl, Arrow to 1-Year Highs

Sometimes more is more, The CW’s Arrowverse crossover event proved, as it does each year, with its “super”-sized ratings.

Kicking off Night 1, Monday’s opening hour drew 2.65 million total viewers and a 0.9 rating, surging 40 and 80 percent from Supergirl‘s previous episode to mark that show’s biggest audience since Jan. 23 and its best demo number since last November’s crossover launch (3.5 mil/1.1).

Part 2 aka the ostensible “Arrow episode” followed with 2.54 mil and a 0.9, nearly doubling that show’s most recent Thursday outing to mark its best numbers since last November’s crossover installment/Episode 100 (3.6 mil/1.3). Last year’s “Heroes v Aliens” crossover averaged 3.7 mil with a 1.3.

All told, The CW enjoyed its most-watched Monday since Jan. 12, 2009 and its highest-rated one in more than six years (since April 25, 2011).
