AMAZON
Amazon in 2014 unveiled its Echo home assistant, a voice-activated speaker, powered by its "Alexa" artificial intelligence program.
Users can ask for news or information updates, as well as ordering goods from the online retail giant.
Echo also serves as a connected home hub which can control compatible appliances, light bulbs and other devices.
Since introducing Echo, Amazon has launched a smaller version called "Dot" and integrated Alexa into its Fire TV devices
