How Many People Know Coke’s “Secret Formula”?

First, and this is not so important; if two people know the formula, then if something happened to one of them, the formula would not be lost. So what they don’t say, but must
mean, is that there are two people who each know half the formula, and nobody who knows the whole formula.

More fundamentally, there is no way in the world that only two people know Coke’s secret formula. If that were really the case, then the shareholders should be filing suit against management. Are firms allowed to just blatantly lie in their advertising? Not that it matters, but I find it strange that a firm would knowingly say something like this when it is completely untrue.

(As an aside, the question of how much Pepsi would pay to get Coke’s secret formula has a surprising answer.)
