The Los Angeles-based producer was one of ten finalists in the online competition where filmmakers competed for a chance to see their video be a commercial during the Super Bowl.
Zabielski's ad, "The Middle Seat," was selected from a pool of almost 4,900 entrants from 29 countries by Doritos to be one of two finalists whose commercials were aired during the big game. The other finalist created an ad called "When Pigs Fly."
The grand-prize winner was selected based on viewer votes and a first-prize winner was selected by Doritos. The runner-up received $50,000.
Doritos posted a photo of the Chicago native holding his $1 million check on its Facebook page on Sunday evening.
Zabielski studied film at the University of Southern California and, while in college, was a finalist in the Coca Cola Refreshing Filmmakers contest. He is currently a director and executive producer at Tosh.0 on Comedy Central.
