I believe GAI was started in the very early 2000s, when the head of grading for PSA left and started his own card grading company. It was primarily a trading card grader, but soon added autograph and game used units.
The company has indeed taken a serpentine route since then, with authenticators and units coming and going, its reputation going downhill. The original authenticators long gone. The original pack grader had to quit when his house burned down. There have even been multiple companies holding the same acronym.
