Jack Dorsey, Biz Stone, and Evan Williams launched Twitter in San Francisco, California, United States, creating a microblogging platform limiting posts to 140 characters (later expanded to 280). This constraint forced concise communication while enabling rapid information dissemination and real-time public conversation. Twitter's hashtag system organized topics dynamically, facilitating social movements and breaking news coverage while also enabling harassment campaigns and misinformation spread, demonstrating social media's dual potential.

Twitter's character limit validated extreme brevity as legitimate poetic form, inspiring tweet poetry and thread narratives. Poets exploited the platform's constraints creatively, developing compressed expression techniques and exploring how limitation generates innovation. The real-time public conversation aspect also influenced documentary poetry capturing immediate responses to events, while the platform's viral dynamics raised questions about literary value in attention-driven economies where popularity may not correlate with quality.
