Mark Jeffery, senior lecturer of executive programs at the Kellogg School of Management, claims that "Big Data" is nothing new, and to prove it, he deconstructed a Land's End catologue, with the help of audience members. With the help of a female audience member we determined that the cover model was around 40 years old (pointing to the wrinkles with a laser pointer) and the catologue is therefore intended for "middle age moms." Additional evidence: a small line at the bottom of the cover that says "Men's XXL and More!" which Mark Jeffery interpreted to mean "you're married and you've got that fat husband at home."
