If you have thought about picking up a dongle over the last several years to enable wireless streaming on your non-smart HDTV, there is an excellent chance you have come across Chromecast. It is essentially a lineup of devices by Google that allows you to stream media to your TV or AV receiver wirelessly. But the underlying Chromecast technology is not just limited to the Google dongles. In fact, you can find it in televisions, speakers, and AV receivers. And it can do far more than just stream online content.
