Jif vs. Jiffy Peanut butter

This one I only just learned about.. the whole Jif vs. Jiffy name.

Back in the 70’s or so, the advertising campaign I can still hear in my head is “Choosy moms choose Jif”… which seems to be the brand name in this timeline, but I’d seen some people remembering it as Jiffy.

For those that cling to Jiffy, do you have any strong memories, like advertisements or anything else you would like to share here?

Thanks!
