McDonald's

McDonald's dominates globally with 40,000+ locations across 100+ countries, earning $23 billion in annual system sales revenue. Founded in 1955 by Ray Kroc in Illinois, its Big Mac even serves as the basis for the Economist's "Big Mac Index" comparing purchasing power parity. The chain serves 69 million customers daily and its McCafe division generates over $4 billion annually. Notably, it operates more than twice the locations of KFC, solidifying its unmatched global footprint.
