For example, I am sometimes served ads for a breathing apparatus, for people who have things like sleep apnea. I have never seen an ad for such a device anywhere online. I have a FB friend who has a breathing issue and uses a device like this.
It seems like I would be a good target for an ad like this, because I have a Friend who might be interested in it, and I might point it out to her. It allows Facebook to charge more for ads, and makes advertisers more interested in advertising.
