Some people have alluded to 'how long' it took Red Bull price share to increase and try to suggest patience based on that. I say 'bull' (lol, double joke...Red Bulls & Bulls9999 :-).
The reason being, Red Bull was establishing a product and market as there was none before....everyone recognizes the market now ('oh yea, energy drink') and it is easier for RMH to fit into that pre-existing market, which wasn't in place when Red Bull was in its infancy.
