Designed to address fan complaints about the visibility of the puck while watching the game on TV, Fox Sports debuted FoxTrax. Made with a built-in circuit board, the modified puck emitted infrared pulses that could be translated into computer graphics on a television screen. On TV, the puck would have a blue halo around it all times, and when it was passed or shot, a red, comet tail trailed behind. Basically it was like watching a live-action video game. Perceived as gimmicky and distracting by hardcore hockey fans, the idea was scrapped in 1998.
