Jack Dorsey first began to develop his early idea for the social media site Twitter in 2006 while working at early Internet tech company Odeo. Spun off in 2007 and expanding rapidly after that, Twitter became a significant component of global society. It became a key part of politics and international relations but was also banned or blocked in some countries.
Twitter went public in 2013 and continued to expand. The COVID-19 pandemic challenged Twitter's handling of misinformation on the platform. Elon Musk took Twitter private in 2022 and later changed the name of the service to X.
