What is the most successful business in the world?

I'm curious, when it comes to the world of business, which company stands out as the most successful? Is it one that's revolutionized an entire industry, or perhaps a brand that's become synonymous with quality and innovation? What criteria are typically used to determine such a title, and how does this particular business continue to thrive and stay ahead of the competition? I'm eager to learn more about the strategies and practices that have contributed to their remarkable success.
