A voice command demostration during the launch event for the Xbox One caused problems for customers watching on their Xbox 360s (their kinect acted on the demo's commands):
I'm pretty sure that they updated her to ignore those. At least, mine doesn't seem to respond to them anymore. She lights up blue to listen, but then goes back to sleep without action. Could be a mere coincidence though, but she still responds to other things on the TV (like Alexi's name from House of Cards). It was like a dad joke: funny at first, but annoying after a while.
