McDonald's was founded in 1940 in San Bernardino, California. It now operates over 36,000 restaurants in 120 countries, serving around 68 million customers daily. McDonald's developed its brand equity over the years through focusing on its core values like quality food and customer experience. It has changed its products and marketing over time to suit different regions and economic conditions. However, in the 1980s, overseas expansion caused it to lose focus on its core values, leading to health issues. But it has since refocused on being more customer-centric and offering healthier options, helping it perform well even during recessions. Going forward, it may face risks from health-conscious consumers and increased competition.
