McDonald`s 

McDonald's is the world's largest restaurant brand, with nearly $139 billion in systemwide sales across more than 45,000 restaurants and over 100 markets. The quick-service chain built its early reputation on speed, consistency, and affordable hamburgers, and today its global menu spans burgers, chicken, breakfast, and beverages that have helped popularize American fast-food cuisine globally. The firm derives the bulk of its revenue from franchise royalties and rent (about 62%), with the remainder stemming from company-operated restaurants across three segments: the United States (39% of systemwide sales), internationally operated markets (35%), and internationally developmental/licensed segments (26%).
