Kids these days
Everyone's a little different when it comes to getting those pesky large numbers into headlines. You can be extra-formal and insist on the zeroes, or you can guess that your audience can figure out B for "billion" and T for "trillion." You can use M for "million," unless the greisly voice of your first editing teacher is shouting from beyond the grave that M really means "thousand," for which you can't use T (above), so you probably fall back on K.
G for thousand is a little more tabloid (in the spinning-front-page-indicates-passage-of-time sense), partly because it's tightly restricted. It doesn't mean "thousand," it means "thousand dollars" (or pounds, for which the OED has a cite from 1958). So somebody at Fox reached one shelf too far for the hed above, but you have to admit it has sort of a grapefruit-in-the-face charm to it.
