CBS's Supergirl episode featuring CW's the Flash crossing over earned at estimated 7.24 million viewers in its Monday evening live debut. That is a 21% increase from its previous episode, but didn't eclipse the ratings for its series premiere or early episodes. This "Worlds Finest" episode was the fourth highest rated episode of the evening, after ABC's Dancing with the Stars, NBC's The Voice, and CBS's Scorpion.
DC's other Monday evening show, Gotham, earned 3.8m viewers on Fox.
Supergirl is on a one-week hiatus, but returns with "Myriad" on April 11.
