Google Cast SDK
The Google Cast SDK enables you to extend your Android, iOS, or Chrome app to direct its streaming video and audio to a TV or sound system. Your app becomes the remote control to play, pause, seek, rewind, stop, and otherwise control the media.
Google Cast is designed for TV, movies, music, and more. Put your best video content on the biggest screens in the house, or bring your audio content to Google Cast for Audio devices and Google Home devices, including the new Google Home Hub.

Case studies
By adding Google Cast functionality to their apps, developers can gain visits, engagement, and/or higher monetization. Here are two real-world examples of how companies have successfully used Google Cast technology.
Comedy Central
The Comedy Central app lets fans watch their favorite shows in full and on demand from mobile devices. The company created a cast-enabled app so users could bring their small screen experience to their TVs. Now with Chromecast, users watch at least 50 percent more video, with 1.5 times more visits than the average Comedy Central app user.
Haystack TV
Haystack TV is a personal news channel that lets consumers watch news on any screen, at any time. The company integrated Google Cast technology so users can browse their headline news, choose other videos to play, and even remove videos from their play queue without disrupting the current video on their TVs. With Chromecast, average weekly viewing time has doubled and customers have dramatically improved their ability to stay informed. One-third of Haystack TV customers now view their news via Chromecast.
