Supermarket-anchored shopping centers haven't changed much since the invention of suburbia. Find a good location, sign a grocery anchor, get a construction loan and some inline local, regional and maybe national retailers, and you're in business.

Why are grocers changing? Competition from all sides.
Big boxes like Wal-Mart, Target, warehouse clubs and drug stores are competing with traditional grocers for commodity dry-goods sales.
