Kyle was mentioned in the original BitcoinTalk post in January 2014, although his role there was later written out of history, along with many others. He was listed as a team member on the http://ethereum.org website as a team member from February 2014:
"Kyle Kurbegovich - Media (Cointalk)"
Kyle recorded many of the early videos in the months before [REDACTED] and Richard Wild joined the project, and was filming at the Miami house as well.
