What is the most expensive ENS domain ever sold?

Could you elaborate on the record-breaking transaction in the Ethereum Name Service (ENS) market? I'm particularly interested in knowing which ENS domain holds the distinction of being the most expensive ever sold. Could you provide details such as the domain name, the exact price it fetched, and perhaps even some context surrounding the sale? Was it a strategic acquisition by a major player in the crypto world, or did an individual investor pay a premium for sentimental value? Understanding the factors that drove such a high price tag would be insightful.
