When I first discovered the products of glacéau, maker of Vitaminwater, it was the summer of 1998, and there were four flavors of Fruitwater. The lemon ginger flavor was strange, at best, but I could drink an entire cold bottle of watermelon water after a run. Cranberry mint was curious and refreshing. They were lovely, with the tiniest hint of color and no sugar: what I'd always wished for in a bottled water.

Cut to 2007, when, in order to cater to the mass market's taste for sweets and the craze for vitamin-enhanced beverages, glacéau's Vitaminwater has been stocked with sugar and color. This summer, Vitaminwater was being guzzled by all my friends' children at family barbecues and birthday parties. The day-glo orange and green look oh-so much like the Kool-Aid and Gatorade we drank in decades past, and I have to say they're just as sweet. The watermelon water I loved has been replaced by four new flavors, all "naturally" sweetened; peach, raspberry, grape, lime. Sounds like Lifesavers! The kooky Whitestone, Queens management has sold (out?) to Coca Cola (NYSE: KO) for $4.2 billion. 50 Cent, famously, had a big payout thanks to his prescient investment in the stuff (he wanted to put his money in something healthier than his rap rivals' liquor ventures). For Coke, of course, it was just the latest salvo in the next generation of the cola wars (now it's enhanced waters and super-premium juices, but it's still the same ol' Coke vs. Pepsi).
