>>5385489>>5385494This is a Nielsen box. It is hooked up to the main TV in the house, so if someone is watching the News on the main TV and wrestling in the bedroom, only the News view is counted.
A Nielsen participant needs to constantly update the box and add/remove additional viewers and input their ages. The "OK" button is a confirmation button, but it also lights up every 30 minutes to make sure that the user is still watching TV. If the user doesn't press the button within a minute, the past 30 minutes are void and not counted.
