Twitter is an omnipresent part of the technology landscape today, but not long ago it was just another startup. Co-founder Jack Dorsey tells the story of how the microblogging site came into existence while he was working at Odeo, a consumer podcasting company in this Entrepreneur Thought Leader Lecture given at Stanford University.

It was there, when the company urged him to come up with new ideas, that the concept behind Twitter was born and the project started. Before long, it was spun out as a separate company and Odeo was sold.
