A Multidimensional Look at TV Advertising:  Chess Anyone?

I don’t know about you, but I’ve found myself making a lot of references to 3D chess lately when discussing the current state of television advertising.  Maybe I’m just weird, or know too many people from too many sides of the business, but in this age of convergence it’s becoming clear that, actually, there are no longer any “sides” at all;  just one vertical, multidimensional “stack” making the game harder to  play -- and harder to win.
