I hadn't even heard about the TFT chapter but the more broadly reported one was the saga with Carmack / Palmer / Zenimax eg ->
- Zenimax bought ID software for >$100m(1) on June 24, 2009.
- Carmack signed up with Zenimax for an earn-out / golden-handcuffs agreement that ended in June of 2013.
- Carmack was enthralled with VR.
- Carmack found Palmer via an internet forum, reached out to get a rift to try.
- Carmack tinkered with the Rift, adding sensors, building calibration, etc. while on the clock / using hardware from zenimax.
- Carmack brought a prototype of the Rift working on Doom 3 to E3 with him providing Oculus with their early press.
- Zenimax realized the extent to which Carmack was enabling Oculus and worked to negotiate equity with Brendan Iribe.
- Oculus sent Zenimax a proposal to discuss a partnership Sept 21, 2012 but never followed up / followed through.
- Carmack quit Zenimax the day his contract was up in June 2013, joined Oculus as CTO a few months later and took his 5 best guys with him.
- FB bought Oculus March 2014, Zenmix got pissed and sued.
From my memory of the early rift I am positive that outside of Palmer it was Carmack's genius that made this viable and Carmack's video lent credibility to the campaign.
No major comment here just a wild history, not unusual for breakthrough & derivative technology!
