Franchising has grown significantly since the mid-19th century with brands like Ford, Shell, and McDonald's. It allows franchisors to expand more quickly while providing franchisees with established business systems and brand names. There are three main types: product distribution, business format, and management franchises. Franchising is important for small businesses as it provides economies of scale, standardized quality, and a proven business model. Both franchisors and franchisees must carefully consider factors like support provided, rights and obligations, and financial viability. Overall, franchising can be a successful business strategy when both parties enter with proper preparation and legal protections.
