DOWN WITH ARIAL!
From Helvetica vs. Arial:
Helvetica was developed by the Haas Foundry of Switzerland in the 1950s. Microsoft distributed a typeface called Arial, a very similar typeface, that comes bundled with every desktop computer
Arial is everywhere. If you don't know what it is, you don't use a modern personal computer. Arial is a font that is familiar to anyone who uses Microsoft products, whether on a PC or a Mac. It has spread like a virus through the typographic landscape and illustrates the pervasiveness of Microsoft's influence in the world.
Arial's ubiquity is not due to its beauty. It's actually rather homely. Not that homeliness is necessarily a bad thing for a typeface. With typefaces, character and history are just as important. Arial, however, has a rather dubious history and not much character. In fact, Arial is little more than a shameless impostor.
