Growth of the Fevertree brand

Call me wierd, but I really like seeing brand development done successfully.
Fevertree, not much more than a year ago was something you primarily found in selective upmarket bars, then you bought the supermarket, then could have in different size bottles/ cans, then saw in mass market advertising, and now can buy in most decent pubs. Even BA have now kicked the mini Schweppes cans from their lounges, which is where this one came from today.
Right now, I can't think of anything else that has had that sort of awareness growth recently.
