What energy drinks are there? Monster, Red bull, rockstar, V, mother and im sure plenty more. Red bull is massive with the alcohol community, they pretty much have that locked down IMO. Also, they have a sugar free version which i think has been around for longer and is popular with all the young chicks trying to stay skinny. I think V might be more popular in Aus cause is it Aussie?
I remember a dude @ work said he watched a doco on the red bull air race IIRC. They basically invented a sport as a marketing promo and it has made them a mint.
