Part of the reason Arial is so dominant is because it's proportioned the same as Helvetica, meaning it can be swapped in to avoid licensing fees without affecting document layout.
Serif fonts were used in print media for ages but when computers came around sans serif became significantly more popular as no longer was there the legibility concern with dodgy pigment applicators etc.
People started to switch to sans serif fonts more and more and would seek out an alternative to the widely defaulted Times New Roman in early days. They'd open the alphebetically sorted fonts list and what did they see at the top?
Arial.
Keep in mind, when personal computing started out, we didn't have a ton of fonts packaged with the system to start with. Just a handful. Arial has pretty much always been there.
The general public was often using Times New Roman or whatever their system's default sans serif font was.
But, designers have cared about things like this for a very long time (ages, as you said.) Arial is joined at the hip with Helvetica, which got a movie[1] because of it's massive cultural impact and it's praise within design circles.
Among professional designers, there were very strong opinions on Helvetica and Arial--almost fever pitch at times. iirc, Arial exists do to the popularity of Helvetica and the background of this goes back to the 1950s. It wasn't just where it was placed in the font selection menu, it was given top billing in that menu deliberately (in Windows.) If you're interested, I think the Wikipedia page for Helvetica (Font)[2] covers it fairly deeply.
That all said, I haven't heard it hotly debated for some time now. The explosion of freely available fonts; popularity of new font families like Open Sans, Noto Sans, etc; and the ability to add custom fonts on the web seems to have slowly killed off the discourse in the last decade or so. I'm not in those design circles as often anymore, though.
Ah yeah I had totally forgotten about Helvetica having such a history. Though I wonder what you mean by putting Arial in that position deliberately - if it was alphabetical (which I remember it being) do you mean that Arial was named as such that it started with A?
I don't mean that it was literally named for the dropdown, just that generally Helvetica was the cause and Arial was the effect. From what I know, it goes back earlier to when Monotype was providing fonts for IBM printers.
From what I know, Monotype was responsible for the name Arial (although IBM called the family Sonoran Sans Serif.) But, even at that point, the intent was to create something that would stand in for Helvetica.
I don't know that the name was selected deliberately to be ahead of Helvetica. But, it's not unheard of in branding to put your product ahead of or near the competition alphabetically. (It was especially important then because people were manually looking up things in phone books and libraries.) I wouldn't be surprised to hear that aspect was considered during naming.
> I don't think any designer has cared about that in the last 30 years. Perhaps not ever.
Not true at all. For instance, Arial was/is typically used as the fallback font for Windows users visiting a website that relied on system sans-serif fonts, while Helvetica shipped with OSX and would be prioritized for those lucky users.
Arial would be chosen by Windows users as good enough because they were already locked in a prison of bad design and terrible typeface rendering anyway, and didn't have other sensible options installed by default.
My point is not that font substitution never happens (it quite clearly does). My point is that no print designer has ever thought "yes, I want Helvetica here, and sometimes we won't pay for Helvetica so sometimes it will look like Arial, and this is what I want". Probably back in the days of PostScript built-in fonts and font cartridges some people thought about that. But since TrueType and embedded fonts happened, I don't think a single designer has ever given a shit about these two fonts being metric-compatible instead of just, you know, picking one and designing with it.
Web design is its own beast and any web designer who wasn't designing, from day one, for different fonts possibly being used without even any regard for metric compatibility wasn't doing their job.
Sure ya, but I don't think it was implied that anyone was talking specifically about metric compatibility exclusively for print design though, just "metrics" compatibility for design in general, specifically game UI, which could be other kinds of documents transferred between people with varying fonts and OS installed
