context_page_description: Chromecast is a line of digital media players developed by Google. The devices, designed as small dongles, enable users with a mobile device or personal computer to play Internet-streamed audio-visual content on a high-definition television or home audio system through mobile and web apps that support the Google Cast technology. Alternatively, content can be mirrored from the Google Chrome web browser running on a personal computer, as well as from the screen of some Android devices.
  The first-generation Chromecast, a video streaming device, was announced on July 24, 2013, and made available for purchase on the same day in the United States for US$35. The second-generation Chromecast and an audio-only model called Chromecast Audio were released in September 2015. A model called Chromecast Ultra that supports 4K resolution and high dynamic range was released in November 2016. A third generation of the HD video Chromecast was released in October 2018.
  Critics praised the Chromecast's simplicity and potential for future app support. The Google Cast SDK was released on February 3, 2014, allowing third parties to modify their software to work with Chromecast and other Cast receivers.
context_section_description: Introduced in September 2015, Chromecast Audio is a variation of the second-generation Chromecast designed for use with audio streaming apps.
  Chromecast Audio features a 3.5 millimeter audio jack/mini-TOSLINK socket, allowing the device to be attached to speakers and home audio systems. One side of the device is inscribed with circular grooves, resembling those of a vinyl record. A December 2015 update introduced support for high-resolution audio (24-bit/96 kHz) and multi-room playback; users can simultaneously play audio across multiple Chromecast Audio devices in different locations by grouping them together using the Google Home mobile app. The feature made Chromecast Audio a low-cost alternative to Sonos' multiple-room music systems.
  With the advent of Google Home smart speakers, the device became tangential to Google's product strategy and was discontinued in January 2019. In addition, the third-generation Chromecast supports Chromecast Audio technology, allowing it to be paired with other devices for multi-room synchronized playback.
  The model number RUX-J42 may have been a reference to the Jimi Hendrix albums Are You Experienced (stylized "R U eXperienced") and Midnight Lightning, which had the internal code J-42. Chromecast Audio was also developed with the internal codename Hendrix.
