A drama series that just wrapped up its second season — and has already been renewed for a third — was just declared to have the highest season-over-season growth of any returning TV drama on U.S. television in the past three years. BBC America announced that “Killing Eve” grew 87 percent in total viewers and 78 percent in the key adults 25-54 demo from season one, based on Nielsen live+7 ratings.

Season two averaged 1.8 million viewers per episode, including 754,000 adults 25-54 and 562,000 adults 18-49.

BBC America noted that the Peabody Award-winning series has also been a force in social media.

“On the night of the season two premiere, ‘Killing Eve’ was the #1 most-talked-about and most searched program on social platforms, and the finale was the #1 most social drama series, to go along with a number of other leading social metrics,” the network announced. “The series generated more than 11 million social engagements across season two and was up double digits in activity over the course of the season.”

Sarah Barnett, president of the entertainment networks group for AMC Networks, commented: “‘Killing Eve’ has captivated viewers in an astounding manner. Season-over-season growth like this would be remarkable at any time; it’s virtually unheard of in television today. There is so much love for ‘Killing Eve’ from a growing base of passionate fans, it’s quite thrilling to witness. Thanks to Sandra Oh, Jodie Comer, Emerald Fennell, and our partners at Sid Gentle Films and the entire cast and crew for an utterly engaging second season. We all can’t wait for another wild, twisted ride with season three next year.”
