text: X, commonly referred to by its former name Twitter, is a social networking service. It is one of the world's largest social media websites and the seventh-most visited website in the world. Users can share short text messages, images, and videos in posts (formerly "tweets") and like or repost/retweet other users' content. X also includes direct messaging, video and audio calling, bookmarks, lists and communities, and Spaces, a social audio feature. Users can vote on context added by approved users using the Community Notes feature.
  Twitter was created in March 2006 by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams, and was launched in July of that year. Twitter grew quickly; by 2012 more than 100 million users produced 340 million tweets per day. Twitter, Inc., was based in San Francisco, California, and had more than 25 offices around the world. A signature characteristic of the service is that posts are required to be brief. Posts were initially limited to 140 characters, which was changed to 280 characters in 2017 and removed for paid accounts in 2023. The majority of tweets are produced by a minority of users. In 2020, it was estimated that approximately 48 million accounts (15 percent of all accounts) were not genuine people.
