Why would they tag their brands of today to the pink panther from years ago? Because they are both pink? Possibly. But most likely it's because these brands are using nostalgic advertising. The demographic targeted for both of these products is the baby boomers. Pink Panther was very popular when they were younger.
Advertisers are playing on their emotions urging consumers to "remember how good things used to be." With the growing concern and uncertainty of the economy don't be surprised if marketers and advertisers start using nostalgia to encourage consumers to return to the past in hopes they will appeal to their emotions in return for a product purchase.
Wonder how long it will be before the Victoria Secret's Pink Line starts sporting the pink panther on their products?
