Battle of the Brains was a Philippine quiz show which aired on RPN 9 from 1992 to 2001 and on PTV 4 in 2001. Considered one of the most culturally influential locally produced shows of the 1990s, Battle of the Brains was open to all elementary, high school and college students nationwide. It was hosted for almost all episodes by David Celdran, with various alternates (including Chiqui Roa-Puno, Cathy Santillan, and Anthony Suntay) taking over in his absence. It was primarily sponsored by Uniwide Sales, Inc. - a major budget retailer of that time- from Seasons 1 (1992-1993) to 7 (1998-1999). It was then sponsored by AMA Computer College from Seasons 8 (1999-2000) to 9 (2000-2001).
