A family business can be anything from a single mom-and-pop store to a global corporation like Red Bull, BMW or Mittal Steel. What marks them out from other businesses is the family dynamics going on within the company and in the boardroom, which can sometimes lead to quirky management styles and unique cultures and procedures. All this is very old-school, but today’s family-run companies include some of the most innovative and successful business around. Wal-Mart, anyone? Ford? Toyota? The Tata Group? Samsung? All multi-generational family-run businesses.
