Netflix has managed to cross the 50-million subscriber threshold for the first time in the history of the company. The online streaming giant reported 570,000 net additions in domestic markets over its second quarter, while international subscribers, its faster-growing segment, pulled in 1.12 million new members. Domestic growth slowed around 10% year over year, though that was less than an expected 18% slowdown. Meanwhile, international subscriptions jumped at a nearly 84% rate, far higher than the expected 54% increase. To its financials, earnings of $1.15 a share missed estimates by a penny and revenue of $1.14 million fell shy of forecasts. TheStreet's Keris Lahiff breaks down the results.
