While ChromeCast is perhaps an evolution of the failed Nexus Q device, it is not a replacement to the more successful Google TV.
While progressing on an update to the Google TV device, the team announced that they “believe there is ample room for both products to exist and succeed” and said that the next update to newer Google TVs’ will support Google Cast (the technology behind the ChomeCast). With the update to Android 4.2.2 for Google TV, streaming content form apps like YouTube and Netflix will come to the Google TV as well as a newer version of the Chrome mobile web browser allowing faster page rendering.
While most Google TV devices will see the update in the coming months, there are some devices that will, unfortunately, not get the update. The devices that will not get the update are the first generation devices including Logitech Revue and Sony’s earlier generation models. This is due to the fact that those devices are built on an Intel chips rather than Marvell Armada processors. Most other Google TV devices and newer Sony devices will get the update.
Even though Google TV had better success than the Nexus Q, it is not saying much about the device. So far, the Google TV device has failed to catch the public despite support from multiple manufacturers; compared to the company ditching the Nexus Q in a couple of weeks after the announcement. With a $35 dongle that does many of the same things as the Google TV, it is hard to say if it will be able to continue.
