We're getting off track here, but Helvetica is a derivation of the Latin name for Switzerland, Helvetia, where it was created. You may be thinking of people referring to it as the "perfect" font because it fits nearly everything - it's used all over the place. McDonald's is probably the most prominent logo associated with Helvetica, but also American Airlines, among many, many others. Microsoft created the knock-off Arial because Helvetica is so successful, but they didn't want to pay the higher price for Helvetica.
