Most of the toys are a variety of foam-based weaponry, with other Nerf products including balls for sports such as American football, basketball, and baseball.

[2] Parker Brothers originally developed Nerf, beginning with a 4-inch (100 mm) polyurethane foam ball.

[3] The inventors' in-house name for the ball was the "falsie-ball," referencing the sculpted padding for bras used to create the appearance of larger breasts.

Marketing slogans promised that one can "Throw it indoors; you can't damage lamps or break windows.

"[4] Some of the first TV commercials for the balls were joint promotions with General Foods' Kool-Aid drink mix, with Micky Dolenz, Davy Jones and Michael Nesmith of the Monkees playing with the balls on a living room soundstage (Kool-Aid sponsored the 1969–70 Saturday morning reruns of the Monkees' 1966–67 TV series).

[22] In 2017, Hasbro released the Nerf Nitro line, which consists of blasters that fire foam cars into obstacles and stunt ramps.

[27] Originally owned and marketed by Larami, Super Soaker is a popular line of water guns.

The current generation of Lazer Tag blasters attach to iPhones or iPod Touch units for enhanced playability.

[29] In June 2013, Hasbro and Grammercy Products unveiled Nerf Dog, a line of Nerf-inspired canine retrieving toys made of rubber, nylon, and plastic.

[33] Nerf has also produced video game accessories for the PlayStation 2, Nintendo DSi, DS Lite, 3DS and the Wii.

Both games feature the Switch Shot EX-3, which doubles as a functional dart blaster and a Wii Remote accessory.

[39] In August 2022, developers Secret Location under licence from Hasbro[40] released the Virtual reality game multiplayer shooter titled NERF Ultimate Championships for the Meta Quest 2 platform.

[41] In February 2023 Secret Location announced on a now deleted developer update on the Meta Horizon Store listing that the studio was shutting down, meaning that support for NERF Ultimate Championships will soon end it will be delisted off the Meta Horizon Store.The game was shut down and subsequently delisted on August 31, 2023.

[46] In November of that year, Hasbro won its patent case against Buzz Bee with the latter banned from producing certain water guns.

[47] In April 2012, Hasbro contacted the Australia-based fan blog "Urban Taggers" for leaking information on unreleased Nerf products found on the Chinese marketplace website Taobao.

[48] Hasbro allegedly tricked one of the bloggers into disclosing his home address for their lawyers to mail him a cease and desist letter.
