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 initiate and control playback of Internet-streamed audio/visual content on a high-definition television or home audio system through mobile and web apps that support the Google Chromecast 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.
