When Did Smoke Alarms For Homes Become Popular

I know most homes and flats have smoke detectors (or should have) but I was wondering around what time did the smoke detectors for homes first come into play?

I mean the battery powered ones you buy and stick up in the hall for your home?

I would think it would be the late 70s. I don’t recall every seeing anyone have one before then.



I don’t remember our house having them until the mid-70s and I remember them being fairly pricey.
