What is the richest company of all time?

Could you tell me more about the richest company of all time? I'm curious to know what company holds this prestigious title and what sets it apart from other companies in terms of wealth and success. What factors contributed to its rise to the top, and how does it maintain its position as the wealthiest entity in history? Additionally, how does the company's financial standing compare to other major corporations and industries, and what impact does it have on the global economy?
