Google Home Super Bowl ad caused some Google Homes to go bonkers

Creating a TV ad for a smart speaker is a toughie. The easiest way to show what it can do is to have people invoke it with voice commands, but then you risk activating the speakers of TV viewers who actually own them. This appears to have happened to Google, whose Super Bowl ad for Google Home caused a great deal of confusion in many users' homes. "OK Google, turn on the hall lights." "OK Google, turn off the music."
