A Roku is a device that connects to your television — or which is built-in to some TVs — which lets you run Internet-connected video apps (or "streaming channels") like Netflix, Disney+ and, now, the KCTS 9 app.
The new KCTS 9 Roku provides users with a wealth of programming options, including many PBS favorites and local fare. And KCTS 9 Passport Members get more to love, with access to an extended catalogue of shows, including many binge opportunities and members-only acquisitions from around the globe. In the U.S., members can also watch livestreams of KCTS 9, WORLD and PBS Kids.
The app is free to download and use. Passport content requires membership.
Here's a video introduction to the KCTS 9 Roku app:
