Twitter founded by Jack Dorsey
Twitter is an online social media and social networking service owned and operated by American company X Corp., the legal successor of Twitter, Inc. Twitter users outside the United States are legally served by the Ireland-based Twitter International Unlimited Company, which makes these users subject to Irish and European Union data protection lawsOn Twitter users post texts, images and videos known as "tweets". Registered users can tweet, like, "retweet" tweets, and direct message (DM) other registered users, while unregistered users only have the ability to view public tweets. Users interact with Twitter through browser or mobile frontend software, or programmatically via its APIs. 
Twitter was created by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams in March 2006 and launched in July of that year. Its former parent company, Twitter, Inc. was based in San Francisco, California and had more than 25 offices around the world. By 2012, more than 100 million users tweeted 340 million tweets a day, and the service handled an average of 1.6 billion search queries per day. In 2013, it was one of the ten most-visited websites and has been described as "the SMS of the Internet". By the start of 2019, Twitter had more than 330 million monthly active users. In practice, the vast majority of tweets are tweeted by a minority of users. In 2020, it was estimated that approximately 48 million accounts (15% of all accounts) were fake.On October 27, 2022, business magnate Elon Musk acquired Twitter for US$44 billion, gaining control of the platform. Since the acquisition, the platform has been criticized for facilitating an increase in content containing hate speech. On December 20, 2022, Musk announced he would step down as CEO once a replacement had been found. On May 12, 2023, Musk announced that he will resign as CEO in approximately six weeks. According to two unnamed sources, Musk will be replaced by Linda Yaccarino, the head of advertising at NBCUniversal.History
2006–2007: Creation and initial reaction
Twitter's origins lie in a "daylong brainstorming session" held by board members of the podcasting company Odeo. Jack Dorsey, then an undergraduate student at New York University, introduced the idea of an individual using an SMS service to communicate with a small group. The original project code name for the service was twttr, an idea that Williams later ascribed to Noah Glass, inspired by Flickr and the five-character length of American SMS short codes. The decision was also partly due to the fact that the domain twitter.com was already in use, and it was six months after the launch of twttr that the crew purchased the domain and changed the name of the service to Twitter. The developers initially considered "10958" as the service's short code for SMS text messaging, but later changed it to "40404" for "ease of use and memorability". Work on the project started on March 21, 2006, when Dorsey published the first Twitter message at 12:50 p.m. PST (UTC−08:00): "just setting up my twttr". Dorsey has explained the origin of the "Twitter" title:
