Hard core designers know the controvery of Arial vs Helvetica. For those who dont, I found this wonderful article at Mark Simpson’s blog. Read the full article here.
”When Microsoft made TrueType the standard font format for Windows 3.1, they opted to go with Arial rather than Helvetica, probably because it was cheaper and they knew most people wouldn’t know (or even care about) the difference. Apple also standardized on TrueType at the same time, but went with Helvetica, not Arial, and paid Linotype’s license fee. Of course, Windows 3.1 was a big hit. Thus, Arial is now everywhere, a side effect of Windows’ success, born out of the desire to avoid paying license fees.
Despite its pervasiveness, a professional designer would rarely—at least for the moment—specify Arial. To professional designers, Arial is looked down on as a not-very-faithful imitation of a typeface that is no longer fashionable. It has what you might call a “low-end stigma.” The few cases that I have heard of where a designer has intentionally used Arial were because the client insisted on it. Why? The client wanted to be able to produce materials in-house that matched their corporate look and they already had Arial, because it’s included with Windows. True to its heritage, Arial gets chosen because it’s cheap, not because it’s a great typeface.”
