At most 40 years ago. I remember turning in our used Coke bottles at Heinen's for the bottle deposit back in the late 1980s in Cleveland, OH. You could tell the reused bottles by the distinctive white chipping pattern around the raised features.

Where I live in western Canada there's still some regional dairies that have reusable glass bottles (they even put the year the bottle entered circulation, they seem to last several years pretty easily).

In Denver, there's a dairy that still does morning delivery in reusable bottles, albeit plastic.

The model still seems to work fine on a certain scale.

The end started about 100 years ago. Some companies held out for many years longer. 40 years ago there was already a lot of plastic, though I'll admit to not having a better timeline
