I will take the leap and say that a small company called Lumosity falls into the world of Marketing.  For, positioned one way, Lumosity would simply be entry #3.2 billion in the category of "Ways to kill time online when you should be productive."

But instead, starting with the tagline of "Reclaim Your Brain" and extending through the core messaging, Lumosity is much more than a nice looking version of any casual games portal.  According to their literature, I will actually get SMARTER by spending time on their site. The multi-layered exercises and puzzles are designed to actively stimulate regions of my brain that have gone neglected, enriching my overall intellectual capabilities. 

So far, I don’t feel smarter, but it has kicked my paranoia level to an all-time high, as I wonder if I am simply a pawn in someone’s giant marketing copywriting experiment.  But, I have succumbed to sucker status, and the exercises are fun, so we’ll see where this gets me.
