The Genesis of Comic Sans

Comic Sans was designed by Vincent Connare for a Microsoft software package called Microsoft Bob, which was supposed to be particularly warm and friendly.  He thought the software needed a warmer and friendlier font than Times New Roman, so he came up with a font that looked rather like it had been carefully traced by a child.  Unfortunately, it didn't fit in the allotted space for the text, so they didn't use it.  (Microsoft Bob, incidentally, was a flop.  The new typeface, though, was used for the Microsoft Movie Maker, which wasn't a flop.)  And, yes, it was designed with comic books in mind (10-15).
