Amazing Amazon really have it sussed. Their latest gadget- The Echo will order online for you if you ask it starting with its name Alexa.
Whenever it hears Alexa it switches on and starts performing whatever task has been asked.
This week a TV station in the US carried a report in which presenter Jim Patton said " I love the little girl saying Alexa ordered me a dolls house."
That was enough apparently for devices across the country to wake up and order dolls houses. It isn't reported how many were ordered but I'm sure the company has thought about the opportunity of advertising on its own Prime network which doesn't require any interaction by the consumer.
