NEW YORK (AP) — Coca-Cola became one of the world's most powerful brands by equating its soft drinks with happiness. Now it's taking to the airwaves for the first time to address a growing cloud over the industry: obesity.

The Atlanta-based company on Monday will begin airing a two-minute spot during the highest-rated shows on CNN, Fox News and MSNBC in hopes of flexing its marketing muscle in the debate over sodas and their impact on public health. The ad lays out Coca-Cola's record of providing drinks with fewer calories and notes that weight gain is the result of consuming too many calories of any kind — not just soda.

For Coca-Cola, the world's No. 1 beverage company, the ads reflect the mounting pressures on the broader industry. Later this year, New York City is set to enact a first-in-the-nation cap on the size of soft drinks sold at restaurants, movie theaters and sports arenas. The mayor of Cambridge, Mass., has already introduced a similar measure, saying she was inspired by New York's move.
