We have often discussed in this blog the 4 major features sets of second screen (To Control, To Discover, to Enhance, to Share - relevant research linked here and here). We have also reviewed what Netflix was experimenting with for leveraging the 2nd Screen as a discovery and control device via DIAL (try opening Netflix on your iPhone while it is also running on your PS3, find the blog here). Finally, we have predicted what a DIAL-enabled world might look like with its major backers (Netflix and YouTube) driving the protocol acceptance into every new device launch since early 2013 (DIAL blog here, 10 predictions here).
Well ChromeCast is the incarnate of all those opportunities and at the same time evidence of where the industry will head with rapid adoption. While we have tried to tell the SmartTV industry that the best implementation for their platform is to be the launch pad for the stream, Chromecast demonstrates that use case out right.
