The Cincinnati Bengals are owned by Mike Brown. He became the team's owner in 1991 following the death of his father, Paul Brown, who co-founded and coached the Bengals. The Brown family owns about 97% of the Bengals, having increased their ownership stake from 57% to 97% in 2011 by buying out the largest minority shareholder. Mike Brown is worth about $5 billion, primarily due to his ownership and operation of the Bengals.
