Nerf (trademarked in capitals as NERF) is a toy brand created by Parker Brothers and currently owned by Hasbro. Most of the toys are a variety of foam-based weaponry, with other Nerf products including balls for sports like American football, basketball and baseball. The most notable of the toys are the dart guns (referred to by Hasbro as "blasters") that shoot ammunition made from Nerf foam. Since many such items were released during the 1970s, Nerf products often feature bright neon colors and soft textures similar to the flagship Nerf ball. The slogan, which has been frequently used since advertising in the 1990s, is "It's Nerf or Nothin'!". Annual revenues under the Nerf brand are approximately US$400 million.
