How Data Can Be Used for Marketing

There have been some really interesting experiments when it comes to data being used for marketing. From the woman who got pregnant and all of a sudden dropped off from any possible electronic channel, I mean she purchased everything that pertained to her pregnancy using cash. She forbade anybody in her circle of acquaintances from mentioning anything about pregnancy on any social media or via email. They didn't have any data points that correlated her to pregnancy until her aunt said something in a private Facebook message then the barrage began. It feels a bit esoteric and a bit magical but it's crazy the things that we can do when we have just a few data points about someone.
