Expectations had been raised by the Memorial Day weekend release of 15 new "Arrested Development" episodes. The comedy starring Jason Bateman and Michael Cera had built a cult following before its cancellation by the Fox network in 2006, after three seasons.
In a letter to shareholders, Netflix CEO Reed Hastings credited "Arrested Development" for providing a "small but noticeable bump" in subscribers. He praised the company for being able to add more subscribers during the first half of this year than it did last year, despite intensifying competition from other Internet video services run by Amazon.com Inc. and Hulu.
Netflix has added 2.7 million subscribers so far this year, up from 2.5 million at the same time last year.
The company received a major boost during the opening three months of the year when it released another series made for Netflix, the political drama "House of Cards." That series earned nine Emmy Award nominations, including for outstanding drama, best actor and best actress. No Internet-only series had previously been nominated in those marquee categories.
"Arrested Development" also had three Emmy nominations.
No one was counting on "Arrested Development" to attract as many subscribers as the February release of "House of Cards" because the comedy came out during the second quarter, a period when Netflix has more trouble signing up new customers. That's because the longer daylight hours and the start of the summer vacation season translate into a smaller pool of people interested in subscribing to a video service.
The second-quarter gains leave Netflix with 29.8 million U.S. subscribers to an $8 monthly service that streams video to Internet-connected devices.
Netflix also added 605,000 international subscribers in the second quarter to boost its total customers outside the U.S to 7.75 million.
Those figures, particularly the U.S. subscriber count, have become Wall Street's focal point, said Sterne Agee analyst Arvind Bhatia. "This is not about the earnings at this point," he said. "It's about how much of the market for Internet video that Netflix can grab."
Netflix's company's DVD-by-mail rental service continued a gradual demise as more people embrace the convenience of Internet streaming instead of waiting for discs to be delivered. Netflix lost another 475,000 DVD subscribers in the second quarter, leaving the company with 7.5 million on that side of its service. Netflix has been pushing people toward streaming because the company believes DVDs are destined for obsolescence and it doesn't want to spend a lot on the business any longer.
Most investors pay little attention to the DVD service either, even though it remains highly profitable.
Netflix earned $29.5 million, or 49 cents per share, in the quarter, up from $6.2 million, or 11 cents per share, a year earlier.
Analysts surveyed by FactSet had forecast earnings of 40 cents per share.
Netflix's revenue climbed 20 percent from last year to $1.07 billion, mirroring analyst projections.
In the current quarter ending in September, Netflix predicted it will add 690,000 to 1.49 million U.S. subscribers.
