To the delight of font-dweebs and typography mavens everywhere, it is apparent that the "interrobang" glyph is being seen more often now in font libraries and thereby may find its way into magazine pages.
The interrobang combines the exclamation mark and the question mark in one and was developed in 1962 by Martin Speckter with the intention of conveying additional information for advertising text.
This item from fontblog, indicates that Microsoft has begun to include the little character in its Clear Type font collection. (Unfortunately, the fonts used for this blog do not contain it.) Here's what Wikipedia says about the interrobang.
