The concept (at least the earliest documented) started in 2016 at WordCamp Miami.
The concept was repeated in 2017 and was made a full hour. Again, people didn’t seem to want to leave – even those that showed up all three days of WordCamp Miami.
For 2018 (WordCamp Miami’s 10th Anniversary), we changed things up a bit. After Matt Mullenweg’s keynote on Saturday, we did a full hour of the gameshow which then was followed by everyone being able to take a 5 minute walk to the after party. The 2018 Gameshow featured a number of variations which are listed on this page.
After 2018 it looks like some camps were beginning to take notice. Several had small trivia contests with the same format and software in 2019.
