From the blue bird to X: 20 years of the sociopolitical loudspeaker that changed the internet

Twenty years after its inception, Twitter, now rebranded as X, has profoundly reshaped global communication, evolving from a simple microblogging service into a significant sociopolitical platform. Launched in July 2006, the platform, initially known for its "setting up my twttr" first tweet by co-founder Jack Dorsey, quickly became a vital tool for citizen journalism, political movements, and public conversation. Innovations like Chris Messina's 2007 proposal for the hashtag (#) standardized topic grouping, while the 2009 US Airways Hudson River landing photo demonstrated Twitter's power for real-time news dissemination, often beating traditional media. The 2010s saw Twitter become central to major global events. Movements such as 'Occupy Wall Street,' Spain's 15-M, and the Arab Spring leveraged the platform for real-time updates and mobilization, drawing the attention of world leaders. Former U.S. President Barack Obama utilized Twitter effectively, celebrating his 2012 re-election with a viral photo alongside his wife Michelle. His successor, Donald Trump, engaged extensively with the platform during his presidency, posting over 25,000 tweets between 2017 and 2021. Twitter has also been the stage for iconic viral moments, including the 2014 Oscars selfie orchestrated by Ellen DeGeneres, which garnered nearly two million likes. More somberly, the 2020 tweet announcing actor Chadwick Boseman's death became the platform's most-liked post, surpassing six million likes. However, the platform's immediacy has also led to career-damaging incidents, such as that of Justine Sacco, a communications director whose pre-flight tweet led to widespread backlash.
