Of all my friends, relatives and other acquaintances I know of exactly one couple who are regular movie goers. The remainder tend to watch in their homes if they watch at all (myself included). I am not counting, of course, the young adult parents who take their kids to every new Disney movie that comes out.
How many millions of friends, relatives and other acquaintances, scattered across the country, in all the over-17 demographics, do you actually have to be able to even surmise that nobody over 17 goes to the movies anymore?
