Elon Musk’s son and the letter X For those that haven’t been paying attention, Musk sort of has a thing for the letter “X.” In fact, this is not his first attempt to name a company after the single letter, as his 1999 money startup was initially called X.com before being renamed PayPal. Company Space Exploration Technologies Corp., where Musk serves as CEO, is also more commonly known as SpaceX and car brand Tesla, where Musk is also the CEO, even features an “X” car model. Perhaps his most infamous use of the letter, however, is as a name for his son with singer Grimes, whose full name was originally reported as being “X Æ A-12 Musk." While Grimes originally tweeted an explanation for the name, which was simply pronounced like the letter “X,” it has since been reported that the couple changed the name in order to comply with state law. What is a Xeet? One of the biggest questions on everyone’s minds since the change: what are we supposed to call a “tweet” now? Many users have guessed “xeet,” a variation on the original term “tweet.” Posts alleging to be screenshots of the Twitter help center page including the term “xeet” have even circulated on the platform, though notes beneath those tweets have marked them false and a quick visit to the official help page shows only the term “tweet” and no sign of “xeet.” Musk answered a tweet (xeet? X?) asking the same question, saying simply that posts would now be called “x’s.” For those worried about grammar, Musk has yet to clarify how “tweeted,” “tweet” or other forms of the work will translate – he “xed?” She “xes?” They “x” often? What about that apostrophe in his answer? The world does not yet know. Did Meta already trademark X? While Musk has already fully committed to the brand transformation, some reports have raised legal questions surrounding the use of the logo and name X, as a number of other companies have already trademarked the letter for their own use. Perhaps most notably, Meta holds a trademark for an “X” logo for “online social networking services" and "social networking services in the fields of entertainment, gaming, and application development.” Microsoft also has an “X” registered for use in similar software and social media spaces, though both companies hold only a few of the many trademarks filed around the letter. While it is not uncommon for many people and companies to have trademarks on similar words, phrases, images, or even letters, the existing rivalry between the brands, especially Meta and Twitter, has led some to speculate a legal battle could ensue. Other changes The transition to “X” is the largest change Musk has announced since earlier this month when he put “temporary limits” on the number of tweets users can read based on their subscription level. Initially, Musk said verified accounts would be limited to reading 6,000 posts daily and unverified accounts would be limited to only 600. A few hours later, he amended this statement by tweeting that rate limits would increase to 8,000 tweets a day for verified accounts, 800 for unverified and 400 for new accounts. An hour after that, he changed it to a limit of 10,000 a day for verified accounts, 1,000 for unverified and 500 for new accounts. Featured Weekly Ad
