Lazer Tag is a brand name for the pursuit game using infrared toy guns, generically known as "laser tag". It was developed by Worlds of Wonder and launched in 1986. As one of America's top hit toys of 1986-1987, Lazer Tag was aggressively leveraged by Worlds of Wonder's retail sales network in an ultimatum to force the Nintendo Entertainment System into retail stores, allowing its smash hit nationwide launch, which prompted Nintendo of America to lead the nation's recovery from the 1983 video game crash and dominate the industry. The Lazer Tag brand is currently a subsidiary of Hasbro's Nerf toy line.

Laser tag is a recreational shooting sport where participants use infrared-emitting light guns to tag designated targets. Infrared-sensitive signaling devices are commonly worn by each player to register hits and are sometimes integrated within the arena in which the game is played.
