It's been interesting reading your comments. I own a marketing agency and create advertising. (Primarily Radio--but some TV as well.)
Advertising works best when the product or service being promoted has a good, solid Differentiating Idea. (Think Nextel's little walkie-talkie feature, Walmart's "lowest price" distinction, or Volvo's ownership of the "safe car" concept.) When this Differentiating Idea is present--and the advertising focuses on it, it works beautifully every time. The problem? Today major ad agencies that handle the really huge, lucrative advertisers spend about 60% of their time trying to dazzle the client so that they are not tempted to accept the advances of competing agencies. This means they are constantly trying to WOW them with clever or sexy ads--instead of helping them differentiate their product and making sure their advertising lasers in on that differentiation.
I know lots of major agency Creative Directors. A large percentage of them are more engaged by, say, writing jokes for Jay Leno--than by creating effective advertising. They are aspiring Saturday Night Live comedy writers. But agencies hire these younger writers to create this "WOW" effect--and too often if falls flat.
That said, I think there's a lot of really good stuff out there too.
