Created by Parker Brothers in 1969, Nerf® (Non-Expanding Recreational Foam) is a solid yet spongy cellular material; the Nerf® ball was introduced in 1970 as the world's first official indoor ball. The material, the ball and the brand have enjoyed non-stop popularity ever since; today the iconic brand is part of the Hasbro toy and game product portfolio. Over time the product line has expanded far beyond indoor balls to include a range of foam-based weaponry including foam dart guns known as blasters; the blasters accept conventional darts along with glow-in-the-dark and suction cup foam darts. Additional products include sports footballs sets, flag football sets, basketball-inspired sets, tournament games and more. Technological advances include neon colors, glowing balls and light beam blasters with laser-like focus; the company continually innovates to increase play value for children of all ages.
