A lot of things have changed in the world since McGregor's last UFC victory. He would go on to have a mega fight in 2017 when he challenged Floyd Mayweather Jr. in a boxing match that went on to do massive pay-per-view numbers before making a return to the Octagon in a failed attempt at reclaiming the UFC lightweight title against Khabib Nurmagomedov. 

But to get a better understanding of how long it has been since McGregor last saw his hand raised in victory, DAZN News lists exactly what was going on in the world at the time.

You may be surprised at just how long it has been.
