Hmm. I was shooting with adjustable cameras starting about 1968 when I joined the Photo Staff at my high school. I would regularly rate Tri-X at ISO 1200 to 1600 in Acufine developer to handle dances and indoor sports events. There was also Kodak 2475 Recording Film that had a base ASA of 1000: we regularly pushed it to 3200 or 6400. (And, wow, was it grainy!) But you really could do concert photos in 'available darkness' with it.I’ve been shooting since around 1972. Fast lenses of the 1960s and 1970s were made to take pictures in low light. This is when maximum film speeds were no higher than ASA/ISO 400. When shooting at or near wide-open with normal to long FL lenses it was just accepted that your background would be blurred, but in my world not many took notice of OOF character. It was simply about the in-focus subject(s).
The first time I heard the word "bokeh" was around 25-years ago when digital began taking dominance over film. It wasn't until then that I paid any attention to OOF renderings at all. In the digital world - even 25-years ago - we could push ASA/ISO speeds to 10,000 or more. Then photographers started shooting fast lenses wide-open in natural bright light – even using neutral density filters to get that bokeh experience. This likely - unbeknownst to me - was going on with film as early as the 1980s when Kodak produced ASA/ISO 3200 film.
Today I believe it's still “a thing” to the point of the character of out of focus rendering is as important – if not more important – than the in-focus character of a lens. So, people still do obsess over the character of their bokeh.
I think the rise of fascination with bokeh, aka 'shallow depth of field', in the digital world happened when the early affordable digital cameras all had tiny sensors that meant it was hard to get the kind of shallow DoF that even 35mm film had at its disposal, never mind medium and large format film. Some photo sites started making a big thing of it, and it became something of a statement to achieve razor thin DoF ... and then people started to notice that not all lenses produced blur that was pleasing. An article or three happened with the newly-discovered-in-the-West Japanese word, and the rest is history. ... 🙂
