Amazon's virtual assistant was already hard at work helping with tasks via its Echo speakers and Fire TV, but now Alexa is getting more control of your television. The online retailer announced today that Alexa can handle more requests on its streaming gadgets, including launching apps, playing selections from Amazon video and add-on subscriptions (HBO Go, Starz, Showtime, SeeSo) and browsing local movie times. Fire TV already offered voice search and Alexa has been available on those devices as well, but this update expands the virtual assistant's workload.
