Which microblogging platform was launched in 2006?

The story behind the answer

Which microblogging platform was launched in 2006? Twitter.

The service began as an internal project at Odeo, a podcast company, after Jack Dorsey proposed a way for people to share short status updates by text message. Work on the project started in February 2006, and Dorsey posted the first message in March: “just setting up my twttr.”

The prototype initially served Odeo employees. Twitter was introduced publicly on 15 July 2006, using the shortened name “twttr” during its early development before adopting the familiar Twitter branding. The platform became known for brief, rapidly posted updates and helped popularize the term microblogging.

The other options belong to different launch timelines: Facebook began in 2004, LinkedIn in 2003, and Instagram in 2010. Another modern wrinkle is that Twitter was renamed X after Elon Musk’s acquisition in 2022, but Twitter is the historically correct answer for a platform launched in 2006.
