Hershey's is Market Oriented.  Although once in a while, Hershey's will release a new product, most of their key products are kept the same.  Market research is done to ensure the product doesn't become out of fashion.  It is well explained in the above ad, Hershey's stand point is that change is bad.  They take pride in their unchanged products.
