It's Academic was an 80s general knowledge quiz show for high school students. Like its intermediate school sibling The W Three Show, It's Academic was hosted by Lockwood Smith. With his Cheshire cat's grin the future Speaker of the House pulled questions from the numbered pockets as students vied for brainiac supremacy and digital watches, encyclopedia sets and calculators. When Smith was elected to Parliament in 1984 he was replaced as presenter by John Hayden. The US format is the Guinness Book of Records-verified longest-running quiz show in TV history.
