Hm, well maybe your dad can address this question:
I once conducted a student directed course about corporate culture for which we had Tod Gitlin as a guest speaker. He stated that the purpose of a good deal of advertising was not to gain market share but rather simply to bolster corporate ego. That it is to say, it was aimed at solidifying a sense of identity and success for investors and employees. He elaborated by noting that many brands are allocated advertising revue regularly, regardless of sales, simply because the company can easily afford it.
By the same token, he also pointed out that many brands are advertised not because the company sees it as essential for success, but simply because the company is afraid to take the chance of not advertising. Again, the argument goes, if they can afford it, why risk not doing it? If it ain’t broke,…
Cocacola is probably the best example. Few products could have a more thoroughly world-wide name-brand recognition, so there is little need to make people “remember” the product. And there is obviously little need for making a “case” to buy Coke (They tried the “new and improved” thing, and it didn’t work.)
At best, what they seek to do is generate positive association with the product, to ward off possible preference for alternatives from 7-Up, but the real answer to that is to just to create their own version, (Sprite, Powerade, etc.) Advertising Coke itself as a drink, however, doesn’t get people to choose Powerade over Gatorade.
Of course, Coke may not be a fair example for this argument, because the brand itself has become (literally, in some places) synonymous with “soft drink.” So really, what Coke wants to do is simply make people consume more drinks. If someone is going to buy a soft drink, chances are–for now, at least–that it’s going to be Coke.
But it makes one wonder: If Coke were to stop advertising, what would happen?
