I just trolled the net and found these culture jam examples.
Just so you all get a better idea of exactly the types of jams that happen and to what extent they deconstruct an existing advertisement and implant a new meaning with the same media tools.
Most of these are American ads – Walmart and Calvin Klein.
One theme targeted often is  portraying realities where people are imperfect and “obsessed” to look as good as the figure on the ad.
I particularly like the ‘branded baby’, highlighting from the moment we are born, we exist in a world of brands and products and those are what identify us as a person.
