Roku files for $100 million IPO, but it's still losing money

Roku has filed for an initial public offering of up to $100 million, according to documents released Friday evening.
The set-top streaming device maker has been growing steadily as more and more people—especially millennials—opt to forgo their cable subscriptions in favor of popular streaming services like Netflix, Amazon, and Hulu. Filings revealed revenue of around $399 million in 2016, up 25 percent from the year before.
