 The name was inspired by a puzzle question that Connare heard at Microsoft headquarters: "Can you make a trebuchet that could launch a person from main campus to the new consumer campus about a mile away?
 Mathematically, is it possible and how?"
 Connare "thought that would be a great name for a font that launches words across the Internet".
 Trebuchet MS was the font used for the window titles in the Windows XP default theme, succeeding MS Sans Serif and Tahoma.
