On the heels of Frito-Lay’s campaign focused on the sources of its products, McDonald’s is going to launch a new promotion in the USA, revolving around the company’s meat and vegetable suppliers, to showcase real people, who help make the fast food chain’s offerings organic. The new push, which includes TV, print and digital, additional paid and earned media, is slated for January 2, and, as AdAge reports, it will be “running sporadically” through the end of 2012.
