Netflix reassures with growth but hits pause in China

US on-demand television service Netflix posted earnings that alleviated concerns over growth, and said it was shifting tack in China due to a "challenging" regulatory environment. Netflix shares soared nearly 20 percent to $119.56 in after-market trades following the release of quarterly earnings figures. Of that number, 39.25 million subscribers were international, a sign that the company was gaining momentum as a global television service.
