A wireless streaming device from Google. Introduced in 2013, Ethernet was later added with an adapter. Chromecast streams content to the TV from Netflix, YouTube, Google Play, Spotify and the Chrome browser via the Google Cast extension. The remote control is the user's smartphone, tablet or computer, whereby content is selected and "cast" to the TV (see casting). At USD $35, the first batch of units sold out immediately. The second-generation model lets users watch the video on the TV while listening to the audio on headphones plugged into their mobile device. In addition, high-res music support (see 96/24) was added along with multi-room capability by plugging Chromecast units into two or more speaker systems. Music Via Chromecast Songs can also be "cast" to the TV's speakers via Google Play Music apps from Android and iOS devices. However, Google introduced Chromecast Audio in 2015 that works with any non-wireless powered speaker. See Chromecast Audio. Chromecast Vs. Android TV The initial release of Chromecast offered Netflix and YouTube as the only third-party movie/video providers; however, more media sources were later added. Android TV, on the other hand, is Google's second-generation set-top box and smart TV platform, and it also runs regular Android apps. See Android TV, Nexus Player and HDMI dongle.
