What does the planet’s second largest brand do when it turns 25? It celebrates like all get out. It celebrates with dance and song and a 12-piece orchestra. It celebrates with cake, fireworks and a limited edition Diet Coke slim can and medallion logo. It celebrates on air during morning drive, with a live remote by Vicki Locke from Atlanta‘s Star 94. It celebrates to reconnect and reignite loyal drinkers’ passion for the brand. It celebrates in the city of its birth, Atlanta, at the new World of Coca-Cola to a laughing, clapping throng of 30,000. It celebrates.
