In 1996, Hamilton County voters passed a one-half percent sales tax increase to fund the building of two new home venues for both the Bengals and MLB's Cincinnati Reds. The Bengals and the Reds previously shared tenancy of Riverfront Stadium (Cinergy Field), but both teams complained that the aging multipurpose facility lacked modern amenities and other things necessary for small-market teams to survive. Paul Brown Stadium was built first to the west; after the Bengals moved, Cinergy Field installed natural grass and was partially demolished to allow construction of adjacent Great American Ball Park to the east. Following the 2002 baseball season, Cinergy was demolished on December 29. The Bengals have hosted four NFL playoff games at Paul Brown Stadium, with no victories.
