Globally, McDonald's is widely regarded as the most successful and valuable franchise system in commercial history, commanding tens of thousands of locations across more than one hundred countries. Its unprecedented success stems from a powerful real estate holding model, standardized operational routines, massive marketing budgets, and widespread global brand recognition. Other extraordinarily successful global franchises include quick-service giants like Subway, KFC, and hospitality leaders like Marriott International, all of which generate immense annual system-wide retail sales.
