"Twitter founder Jack Dorsey had a background in messenger culture. He had even launched a dispatch software startup called D-Net, back in 1999. He was also captivated by his friends [sic] status messages on AOL Instant Messenger. He wanted to combine the two. And in an era when AIM was king, he did just that."
