Advertising always has been, and always will be, a black art. The percentage of time, effort, and money that works for one company might fail dramatically for another. I disagree, the great ad agencies have been around for decades... far longer than any software company to date. It's an art that can be mastered and requires creative genius, the right brain equivalent of an engineer. The problem is, it usually takes two to tango. Therefore, many times bad advertising is the result of 1) insufficient research by the marketer, 2) poorly executed product, or 3) a client that thinks he knows what he's doing.
