CNBC’s Jim Cramer on Tuesday reflected on the legacy of Tim Cook, arguing that the longtime leader of Apple

achieved something many in corporate America consider “almost impossible.”

“You have heard a lot about Tim Cook today and for good reason,” the “Mad Money” host said. “He built the greatest consumer-based enterprise in history.”

Cook, who succeeded Steve Jobs and will be replaced by hardware engineer John Ternus in September, faced early skepticism about whether he could maintain — let alone expand — Apple’s dominance. But under his leadership, the company’s stock increased roughly 1,900%, as of Monday’s close, while also deepening its connection with customers in ways that Cramer said are rare in modern business.
