Definition: Chromecast

A Wi-Fi-enabled streaming video device from Google. Chromecast is a small module that plugs into the HDMI port of the TV set. Launched in 2013, the $35 Chromecast sold out immediately because it transferred any content displayed on a user's device to the TV screen, known as "casting." It also added Netflix, YouTube and other content to the TV, and Google's Chrome browser can be cast as well. Songs can be cast via Google Play Music apps in Android and iOS devices. See screen mirroring.

In 2015, Google introduced an audio-only Chromecast that worked with any powered speaker, but it was discontinued a few years later (see Chromecast Audio).

Ready to Cast

Chromecast is always in a ready state waiting for movies/videos, music or Web pages to be "cast" from the user's phone, tablet or computer to the TV.

HDMI Video and USB Power

Chromecast plugs into the TV's HDMI port and gets power from USB. The image (top) from Google shows a first-generation Chromecast with ports conveniently close. In the real world, such as plugging a Chromecast into an A/V receiver (bottom), connections are not always so aesthetic. (Top image courtesy of Google Inc.)
