The actor left in season 19 of the popular show, and opened up about his decision to leave the program for a special featurette on the show's season 19 DVD release.
He sat down to discuss the legacy of his character, as well as his thoughts on how the show wrapped up his storyline, and admitted that the opportunity to tackle "fresh" and "challenging" material is what kept him returning to the drama every season, alluding to the possibility that he felt that after almost two decades on the show, he no longer felt that was the case.
Following Mark's onscreen departure, Showrunner Steve Binder released a statement that heavily suggested Gibbs could make a comeback in future seasons.
