Behind the scenes
This appears to be a reference to the Quake series of games and a mix of both original release date of Quake, and the original QuakeCon which was inaugurated in August 1996.
As well as a reference to basic concept of Quake II/Quake III Arena/Quake III Team Arena/Quake Live as a Arena based 'athletic' battle sport..
Quake symbol can be seen on a poster in a locker in a locker room of the UAC Advanced Research Facility in Doom 2016.
