I found this over at Garry Tan’s site. Garry happens to be the co-founder of Posterous (my primary publishing platform).
Being in the PR / Social Media biz, I’ve helped clients bring to market disruptive technologies that, well, disrupt.
Take VoIP or WiFi as an example. I worked with AudioCodes and Envara (no more links to Envara as they were acquired by Intel) for many years before their respective technologies took hold in a market that took years to take hold, be meaningful and return an exit (AudioCodes did go public).
Following AudioCodes, they are on to another great disrupter: HD Voice. Not over night. But over time, I think this is a great disrupter. Something Gartner missed in this chart.
