In 2003, Mayor Bloomberg took a sweet sip and christened Snapple the “official beverage of New York City,” as part of an unsuccessful marketing agreement giving the beverage giant exclusive rights to peddle high fructose corn syrup-laden drinks to the city’s schoolchildren. Now with that contract completed, the city is free to change course and attack the sugary drink maker, or at least its likeness, in a series of new Department of Health ads declaring: “Don’t Drink Yourself Fat.” Going up on subways today, the PSAs show sugary streams of Snapple, Coke, and Gatorade-style soft drinks morphing into gleaming blobs of fat, bubbling over a veiny, yellow, lard-filled glass. |NYDN|
