Best Buy is an American electronics retailer headquartered in Minnesota. It operates over 1,000 stores across the US and has over $50 billion in annual revenue. However, its market share has declined due to increased competition from Amazon, Walmart, and Apple. Best Buy is working to adapt by closing some stores, focusing more on online sales and services, and improving the customer experience. It faces challenges from showrooming and must find ways to remain competitive against other retailers.
