Twitter started as twttr. It was a text messages broadcasting app by people from Odeo.
Odeo was Noah Class' podcast platform. When Apple launched iTunes, Odeo began to fall rapidly - nobody needed a podcasts-only app. Glass and his team started organizing hackatons to save the business. One of Ode's workers, Jack Dorsey, came up with the idea of twttr, a new Ode's product. Glass liked and supported that.
At first, twttr was meant for teamwork and internal communication, but soon media like TechCrunch picked up the trace. It gave twttr its first thousands of users. Once the guys bought the Twitter.com domain, they changed their product's name to Twitter as we know it today.
