Vincent Connare, who when he worked at Microsoft created the ubiquitous typeface Comic Sans, does a wonderful stand-up presentation of his handiwork and a small sampling of its overuse and misuse around the world. Vinnie’s original brief was to make a typeface for the word balloons in Microsoft Bob, the overly helpful little animated character in Windows 95, that would be based on lettering in comic books. He succeeded beyond his wildest dreams.
Comic Sans is one of those typefaces, like ITC Souvenir, that’s too successful for its own good. It’s curved and “friendly” in a way that irritates typophiles but appeals to everyday users. And it’s on everyone’s machine, so it’s available to be misused in every way conceivable.
