Card Sharks is an American television game show created by Chester Feldman for Mark Goodson-Bill Todman Productions. Two contestants compete for control of a row of oversized playing cards by answering questions posed by the host and then guessing if the next card is higher or lower in value than the previous one. The concept has been made into a series four separate times since its debut in 1978, and also appeared as part of CBS's Gameshow Marathon. The primary announcer for the first three series was Gene Wood.
