Courier and Courier New
“A letter can be just an ordinary messenger, or it can be the courier, which radiates dignity, prestige, and stability. “
– Howard Kettler
Courier typeface is a monospaced font (a font whose letters and characters each occupy the same amount of horizontal space) designed to resemble the output from a strike-on typewriter. It was designed in 1955 by Howard Kettler. It was later redrawn by Adrian Frutiger for the IBM Selectric Composer series of electric typewriters. The company IBM chose not to secure legal exclusivity. This lead to Courier becoming a standard font in the typewriting industry.
In the 1990’s Courier became useful in the electronic world. Being a monospaced font, it was used in situations where columns of characters needed to be properly aligned. It became an industry standard for screenplays to be written in 12 point Courier, or something close to the font. Courier New was introduced with Windows 3.1. Courier New has higher linen space the original Courier. Courier New had been the U.S state Departments standard typeface until 2004. It was then replaced by 14 point Times New Roman. Times New Roman was said to be more modern and legible.
