In 2006, a quiet developer and amateur designer named Jack Dorsey stood in a playground in San Francisco and pitched an idea to his colleagues: what if you could send a single text message that would instantly broadcast your status to all your friends at once? That sketch became Twitter.
The SMS Character Limit Hack
Originally called **twttr**, the platform was designed to work entirely over mobile SMS protocols. Because carriers restricted standard texts to 160 characters, Dorsey established a **140-character limit** for posts, leaving 20 characters for the username. This constraint proved to be a masterstroke, forcing users to write brief, rapid updates.
Twitter evolved from a simple status tool into the dominant real-time newsroom of the modern age, proving that speed and brevity could beat massive long-form networks.
