Redirected from: Confinity

Definition: X.com


The rebranding of the twitter.com URL after Twitter was purchased by Elon Musk in 2023. Prior to May 2024, both twitter.com and x.com pointed to the new x.com domain. The iconic bird logo was replaced with an "X." See X/Twitter and Twitter.

The X platform is expected to add financial services, combining social media and payments processing like China's leading "everything app" (see WeChat).

Several X Names
Musk is obviously very fond of the letter X. In 1999, X.com was the name of the online bank he founded with Harris Fricker, Christopher Payne and Ed Ho. A year later, x.com merged with Confinity Inc. and eventually became PayPal. SpaceX is the name of Musk's very successful rocket ship company, and Musk even named his daughter X (see X AE A-12). Also spearheaded by Musk, xAI was formed in 2023 to "understand the universe" according to the company's website. See XAI, SpaceX and PayPal.

Does a Retweet Become a Re-X?
Rebranding is often done without regard to how the new name will be used over time. After 17 years of Twitter terminology, will "tweets" and "retweets" really go away? "Post" and "repost" are their official replacements; however, there are many other Twitter terms (see Twitterese). See naming fiascos.
