As diverse as CPG retailing is, there are certain questions that almost everyone in the industry has to deal with.

How big should a store be? How many store sizes can a company deal with? How can a retailer offer health services in the age of Obamacare? How much is the market polarizing, and which pole offers the best opportunity?

This special issue of Retail Leader looks at four trends in CPG retailing, and offers examples of how leading retailers are dealing with each trend. They are:

Store formats. Smaller "Neighborhood Market" stores have been a bright spot for Walmart. Kroger, meantime, is trying out an intermediate size between its full-size supermarkets and its convenience stores.

Health care. CVS got a lot of attention for stopping tobacco sales, but its reinvention as "CVS Health" runs deeper. Meantime, Walmart is taking preliminary steps toward in-store clinics that have the potential to revolutionize health care.

Market bifurcation. Aldi's model for discount groceries has been so successful that the company is ramping up its expansion plans in America.

Mergers and acquisitions. Kroger's purchase of Harris Teeter gives it a new demographic and geographic reach. The acquisition of Safeway and its merger with Albertsons cemented Safeway's position as America's No. 2 chain.
