2 — By Katie Lee — Smoothie King unveils its next chapter with a new brand campaign and in-store transformation, celebrating over 50 years of balancing nutrients and flavor. In 1973, Smoothie King introduced a bold new F&B category to the world, literally coining the term “smoothie.” Since then, the king of smoothies has grown to more than 1,200 U.S. locations — and more than 200 new store commitments — with over 1,500 available trade areas in its development pipeline.
