Once a niche player selling a very niche product, Morton Grove, IL.-based Lifeway Foods is about to step onto the national advertising stage in a big way. Founded in 1986 and now the nation's largest supplier of the cultured dairy product called kefir, Lifeway will air its first-ever national TV spot from the boutique Distillery Project Chicago ad shop on Jan. 11, during the 2015 Golden Globes broadcast hosted by Tina Fey and Amy Poehler .
