That's exactly what I was referring to in my original post.
I seem to recall it was about 1973.

The next year saw the introduction of the Canon AE-1 and that became the hot camera in the amateur market. Canon sold more versions of the AE-1, AE-1P, AV-1, A-1, T50, T70, T90, etc. than any other brand.
Everyone else began playing catchup.
It wasn't until ten years later, when the Minolta Maxxum was introduced, that Canon's lead began to erode a bit.
Olympus, Fuji, Konica, Pentax, and Yashica, never fully recovered.

Only four lens mounts from those days remain today in the digital world: Canon EOS, Nikon, Pentax, and Sony (Minolta Maxxum).
From about 1965 to about 1995 were the "glory" years for 35mm SLRs.
The transition went from fully manual to built-in metering to automatic exposure to auto-focus.
Those were the days!
