Amazon, Google using CES to tout personal assistants

Boston Herald 

The flash of the CES technology show in Las Vegas is all about robots, drones and smart gadgets. But its subtext is all about Google versus Amazon. Both companies usually shun conventions like CES, preferring to debut gadgets at their own press events. But these tech giants have built an imposing presence here this year as they work to weave their voice-operated digital assistants more deeply into our personal lives. Google has plastered digital billboards and the Las Vegas Monorail with the "Hey Google" wake-up command.
