Cam and I really don't watch much commercial television any longer and since I gave up making my $$$$$ in the ad business, don't follow these trends....

but guess what? - just take a look at the average GPI of high school graduates these days and see how many are going on to four year education - and I'll bet you'll have the demographic your looking for.... not to mention that the target audience of most "broad" marketing campaigns are going after those with the most to lock in - the 18-25 year olds (before brains have stopped growing)

only a hunch... (don't take my word for it...)
