Roku Inc. has reported that it has sold more than 8 million video-streaming devices since its first box hit the market nearly six years ago.

The Roku stick is pretty simple to attach, but you do need to power it up with an AC adapter in order for it to work. Once it’s plugged in you use a Wi-Fi controlled remote control with your TV to control the device. Chromecast, on the other hand uses your smartphone as opposed to a remote. However with Roku you have the option of using either.

Both of these devices can stream from your Netflix account, but you do need to have an account that you pay for already in place. It also works for Amazon Prime, or HBO Go and other types of streaming video services.

What I like about Roku over Chromecast is that at the moment it has far more content. It has about 170 channels. I think over time Chromecast will grow, but for now, Roku is ahead on content.
