Google Chromecast Review: A streaming device that gets better the more it knows

Once upon a time, watching TV involved picking up a remote control, pressing the power button and flipping through channels.

Boy, have things changed. When you watch TV with the new $50 Chromecast streaming stick from Google, the search giant tries to find content that you may want to watch based on what it knows about you.

Before you get started, it wants you to take these steps:

1. After plugging the streaming stick into the back of your TV, you press and hold two buttons on the white remote control.

2. On your smartphone, you download and open the Google Home app, log in with your Google account and enter the home address where you are using the Chromecast.
