McDonald's serves over 70 million customers per day globally. It started in the 1940s with its famous 15 cent hamburgers. McDonald's stands out with its unique golden arches symbol and mascot. It has attracted many customers over the years through affordable menu items like its $1 menu and by introducing localized flavors. However, McDonald's also faces challenges around food quality issues and paying low wages to employees, despite being extremely profitable. It continues to invest in technology and charity efforts to build its brand equity over the long term.
