Chromecast is a different approach to extending media.  Most devices (Roku, FireTV, AppleTV) all requires proprietary apps to be installed on their devices.  For example, Netflix developers would have to create a port of the application to be used on each media device.  Obviously (or maybe not), you can&#x27;t install apps on a Chromecast.  The only thing it does is receive an instruction from a device on your wi-fi network.  That instruction comes from a mobile app (such as Netflix) that implements the chromecast api, a way easier approach than porting the entire application.<p>It&#x27;s amazing and simple.  Chromecast is on to something...
