Building Narratives into products

With the invention of TiVo and DVR's, consumers now have a choice of whether or not to watch commercials. Businesses have naturally responded by shifting advertising from the 'in-between' parts of the show to the show itself via product placement. But what types of placement are most effective?

In Martin Lindstrom's book, Buy-ology, Lindstrom analyzes the effects of different types of product placement and comes to the conclusion that those products that have a significant role in the process of the show are the ones that 'imprint' themselves upon consumers' brains - at the expense of OTHER brands.

Doing a quick mental exercise of product placements that I could remember (limiting myself to TV Shows) I came up with this list within a minute or two:

-Canadian Club - Mad Men. Don Draper has a drink of it in virtually every episode and consumes too much of it in many. The bottle is prominently featured on his desk.
-Chrysler Lebaron - Seinfield. Specifically, I think about the episode where George Costanza bought a Lebaron because he thought it belonged to Jon Voight.
-Cadillac Eldorado - Seinfield. Jerry bought his father a Cadillac and the neighbor crashed it into a swamp.
-Cool Whip - Family Guy. Stuey mispronounces it heavily.
-IPod - Family Guy. Jillian gets married and confuses her box of chocolates with an I-Pod.
JujiFruit - Seinfield. Elaine gets a box on the way to visit her boyfriend in the hospital. Her boyfriend is miffed that she stops for candy.
Sponge - Seinfield. Elaine's preferred method of birth-control runs in short supply and she evaluates prospective sexual partners based on whether they are 'sponge-worthy'.

In my lifetime, I have probably been exposed to thousands more (Lindstron estimates that over a 66 year time-span, the typical American is exposed to 2 million commercials) but these are the ones that stick out - the ones that build a narrative. Simply showing the product isn't sufficient - to stick in consumers' minds, a narrative that fits the story must be built in.
