Actress, director, and producer Elizabeth Banks recently hosted a series of podcasts and films featuring mid-cap companies that are re-inventing themselves in the face of business challenges. These spots were part of the series CrazyEnough2Work, created by State Street Global Advisors. The most valuable lesson she learned over the course of these interviews came from Dunkin' Donuts. The company says its getting back to its core business ? coffee ? and dropping the "Donuts" in its name.
