C's Candy

C's candy is obviously small in the context of Berkshire's currently expansive operations but has long been one of your favorite businesses. Can you explain why C's was able to grow its profits through the 70's, 80's and 90's but not so far in this millennium? Did something change about the business for instance the growth in demand for box chocolates or its market position? Could you or Brad Kinsler discuss whether the relatively recent geographic expansion could help reignite C's growth? Thank you.
