In the 1970s, you could hardly open a magazine or pass a
billboard without seeing the advertisement for Virginia Slims
cigarettes that said, "You've come a long way, baby." It usually
featured a flowing-haired, liberated modern woman alongside some
drudge of a generation or two earlier, pegging out laundry. The
implication (as well as that smoking was good for you) was that
women had revolutionised their lives in unprecedented ways over a
few decades, and that a great broad path of such freedoms still lay
ahead, along with some fab new haircuts.
