Netflix added nearly seven million new customers in the three months to September, bringing its total to more than 137 million members worldwide.
The growth was stronger than expected, prompting the firm’s shares to jump more than 10% in after-hours trade.
It came as the firm premiered a record amount of original programming, including new seasons of Orange Is The New Black and BoJack Horseman.
Netflix is among the first of the major US tech firms to report earnings.
Investors were looking for signs of a rebound at the company after an unusually weak second quarter, which had fanned worries about the online streaming firm’s future.
