Roku shares popped more than 20 percent after hours on Wednesday after the company posted a narrower loss than Wall Street estimated, thanks to better-than-expected sales in its first earnings report as a public company.

The streaming technology company went public in late September in a $252 million IPO. The company's fortunes have risen alongside services like Netflix that have moved TV viewership online, often using devices made by Roku. Netflix also reported better-than-expected financial results last quarter.
