Betting I’ve reblogged this before. Betting I’ll reblog it when it turns up again.
In addition to the print terminology stuff: the visual shorthand icons and ad graphics for something about writing are still often pen-nibs, fountain pens and typewriters…
…while graphics of a monitor, keyboard and mouse remain visual shorthand for computing…
…even though most writers now use monitor / keyboard / mouse or even laptop / touchpad.
In addition, headers for “this blog / website is about writing” are often in one of the many imitation typewriter fonts complete with smudges, or just Courier.
The start and end call icons on most / all smartphones is still the handset of a classic desk telephone, and sometimes the open-app icon is a complete phone.
The term “hang up” for “end the call” refers to something even older - one of these…
And of course the Save icon is indeed a 3½ inch floppy disc.
Why it wasn’t a 5¼ floppy is a mystery. The icon version is just as distinctive.
Also, why various OP updates never changed “Save” to the graphic of a CD / DVD or flash drive is another mystery, and nowadays a Save icon should probably be a cartoon cloud.
Graphics and terminology are funny things.
