Elon Musk Obsession & History with the Letter X . Continuing his legacy of 25 Years He Renames Twitter Social Media Platform .

Elon Musk is continuing his career-long fascination with the letter X as he announces a dramatic rebranding of Twitter.

Musk's affinity for the letter in both his professional and personal life has been growing for 25 years, though he has rarely ever given a reason.

Now, it looks like one of the largest social media apps will soon be known by the singular letter that has long been a Musk obsession. 'Looking forward to working with Linda to transform this platform into X, the everything app,' Musk recently wrote on Twitter, referencing new CEO Linda Yaccarino.

One of Musk's first ventures was known as X.com, first launched by Musk as an online banking and financial services platform in 1999. A year later, he was forced to step down from his role as CEO of the firm.

Three years later, he made $165 million when the site, by then merged with PayPal, was bought by eBay.

Musk would later buy the domain X.com back from PayPal in 2017. That site now directs people to Twitter. 'Thanks PayPal for allowing me to buy back X.com! No plans right now, but it has great sentimental value to me,' Musk wrote on Twitter in 2017, That domain was Musk's first major use of the letter X, but not his last.

Musk is also the founder and CEO of SpaceX, which is formally known as Space Exploration Technologies Corporation.

He founded the company in 2002 and it recently launched its $3 billion - a test flight which was deemed a great success even after it burst into a spectacular ball of flames.

SpaceX and even NASA all hailed the mammoth new rocket's maiden flight as 'exciting' and a success.

Tesla, where Musk is CEO, sells the Model X, which went on commercial sale in 2016. The car, a mid-sized luxury crossover SUV is recognizable by its falcon doors.

Musk has announced he is rebranding Twitter effective immediately - changing the site's name to 'X' and the platform's iconic blue bird logo to the letter as well

Hours earlier, Musk alluded to some smaller but still seminal changes to the platform, with various photos containing some stylized form of the letter x

Musk, in trademark fashion, looked to play along with storm of sarcastic posts, asking his some 149million followers within moments: 'What should we call tweeting?'

Musk and his former partner, the musician Grimes, raised eyebrows in May 2020 when they revealed the name of their newborn son: X Æ A-12. The billionaire is said to have given the little boy, three, the nickname X for short.
