Which event helped Twitter gain major attention in 2007?

The South by Southwest festival helped Twitter gain major attention in 2007.

At the South by Southwest Interactive conference in Austin, Texas, Twitter was prominently used and promoted through large display screens showing messages from attendees. The visibility helped turn the young service from a relatively obscure messaging experiment into one of the most talked-about social platforms among technology enthusiasts.

Twitter had launched publicly in 2006, but its early growth was still uncertain. The 2007 conference provided a concentrated audience of influential bloggers, developers, journalists, and early adopters. Many attendees experienced the service in a shared event setting, where short public updates were especially useful.

South by Southwest was not Twitter’s launch event, and the service did not originate there. Instead, the conference is remembered as an important early growth milestone. Later expansions came through mobile use, breaking-news coverage, celebrity participation, and political communication.
