LOS GATOS, Calif. — It is April 9 just before midnight in the war room of Netflix’s headquarters here, where the smell of popcorn fills the air and a team of engineers, social media experts and other specialists starts counting down the seconds until the new “Daredevil” superhero series goes live on the streaming service.

At the stroke of 12, applause breaks out in the room. Flutes of Champagne are passed around as the Netflix team checks that the series is available for binge watching across devices in more than 50 countries around the world.

“Daredevil” is the 17th Netflix original series to make its debut this year, representing a bold bet by the company to significantly increase its investment in exclusive programming. Just three years after Netflix started streaming its first original series, “Lilyhammer,” the company is planning 320 hours of original programming in 2015. That is about three times what it offered last year.

Reed Hastings, Netflix’s chief executive, is a connoisseur of them all, though he admits some run more to his tastes than others. During an interview the next afternoon, he said that he had watched the first episode of “Daredevil,” but called it “too violent” for him.
