Coca-Cola's chairman and Chief Executive Officer Muhtar Kent has publicly committed the company to getting them back. "We believe in the North American market. We believe in the demographics, we believe this is a growth market," he told investors during the fourth-quarter earnings call in February. The company is doubling down on its carbonated soda line and is in the midst of a $1 billion advertising push. Its current World Cup campaign, which heavily focuses on the classic Coca-Cola brand, is the most expensive, all-encompassing marketing campaign in the company's history. It won't disclose how much that is, but the Wall Street Journal put the figure at around $600 million. At the moment, Coke Life doesn't have a U.S. debut date. Given the company's heavy investment in stevia-based drinks—in 2007, Coca-Cola and Cargill teamed up to create Truvia, a consumer brand of stevia sweetener—it seems likely that the drink will soon see much wider release.
