Here in Canada we have both potatoe chips and potatoe crisps

. The main difference being that crisps are baked and chips are fried. Since the idea of consuming too many calories has become so important to many, the baked goods are more appealing than the deep fried ones. Anything baked sells very well nowadays.
I don't know about south of the border, but we don't call "Pringle" potatoe chips
"chips" any more. They are called
crisps to make you think you are eating less fat. I think the crispy quality is the same in both baked and fried chips. Both yummy!!!
