The Hydra television set is used by Ben in "The Glass Ballerina" to prove to Jack that the Others have contact with the outside world since the crash of Oceanic Flight 815. Ben uses the television to play a tape of the Boston Red Sox winning the 2004 World Series. The Hydra television is mounted on a wheeled cart and is attached to a 1985 SONY VO-5800 U-matic video recording device.
