Forecast = to predict
>Whispers numbers are the numbers you get Friday night that may give you an idea of the kind of >box office a movie did.
Who came up with that definition? As far as I know, HSX is the first and only place to apply "Whisper Number" to movie box office gross. The name is used editorially as one author's forecast/prediction of weekend box office just as financial analysts make forecast/predictions on company earnings before they are reported.
