The origin of Twitter starts with Evan Williams and Noah Glass. The two Silicon Valley entrepreneurs came together to create Odeo, a podcasting platform that would eventually become obsolete thanks to Apple iTunes. This didn’t stop Evan Williams from successfully growing Blogger, which led to a multi-million dollar sale to Google in 2003.

Meanwhile, a side feature of Odeo was set to become the latest microblog and social network platform. Known first as Twttr, the service allowed users to send short messaging service, or SMS, to groups. Six months later, the name was changed to Twitter.

Twitter is now known as a social networking and online news site. It offers easily digestible content and allows you to search for and follow friends, celebrities, and business accounts. It’s been described as a marketing tool, amateur news reporting platform, and social messaging service. In 2020, had over 5,500 employees and total assets over $13.3 billion.

The Founding of Twitter: How It Happened

Evan Williams and Noah Glass worked together at Google before deciding to leave and become co-founders of Odeo. Evan Williams also brought along another coworker, Biz Stone, to work on the project. Jack Dorsey had a chance encounter with Evan Williams and decided to reach out. He was added to the Odeo team.

Unfortunately, the launch of iTunes, with its podcast feature, made the Odeo venture obsolete and struggling to get off the ground. Twttr was created in 2006 to offer SMS status updates. Users could use the SMS short code “40404” to send updates to a small group.

The South by Southwest convention became a key moment in the growth of the service. During the Austin, Texas conference in March 2007, the number of daily tweets grew from 20,000 to over 60,000. The number of users and value of the company climbed significantly after that critical conference.
