The first-ever tweet made on X (formerly called Twitter) has resurfaced as the platform, now owned by Elon Musk, turned 20. 'Just setting up my twttr," Twitter Co-founder Jack Dorsey had posted at 2:20 am on March 22, 2006. He later sold the post as an NFT for $2.9 million (over ₹27 crore), but its value has reportedly plummeted now.
