Pretty much every American generation has grown up with its own flavor of beverage ads.

For the Flower Children, it was all about Coca-Cola, climaxing with the famous “I’d Like to Buy the World a Coke” TV ad.

For Gen X-ers, there was the Pepsi Challenge blind taste tests, which led to the development of fiendish sugarwater New Coke (for an interesting analysis of the story, pick up Malcolm Gladwell’s Blink).

Whether being told to do the Dew or be like Mike, thirsty Americans have never suffered a drought of clever and usually very expensive beverage campaigns.

So it’s refreshing to see a drinkmaker engage its audience through social media rather than drench it with in-your-face commercials.

In September, the beverage brand Vitaminwater (which is owned by Coca-Cola) launched a Flavorcreator tab on its Facebook fan page and began soliciting its fans (now over a million) to design the new flavor. They also created this genuinely funny commercial, starring their spokesman, Steve Nash — quite possibly the only famous athlete ever with actual comic timing. (Sorry, MJ.)

The winning flavor: black-cherry lime with a hint of caffeine. And the name: Connect. That’s surely a reference.

Here’s the fan page announcement Vitaminwater posted yesterday.

Personally, I like Vitaminwater — though I mainly stick to the low-cal Vitaminwater 10 line. Carbonation + sugar = unhappy ’sophagus. But I love vitamins, and I LOVE caffeine, so I think I may have my new favorite drink (if they make a Connect 10). But taste aside, this was pretty much a model of a crowdsourced social media campaign.

Bottoms up.
