Prior to the early-1950s, marshmallows were usually either bars or small squares, rather than the modern cylindrical extruded shapes.

In 1948, Doumak, an American food company, invented and began patenting the modern extruding process,[1] which Kraft would start using in 1953,[2] and by 1958, begin branding as "Jet-Puffed".

The rocket toured U.S. cities through 1959, and had young people waiting in long lines for their chance to sit at the control panels.

[3][4] In 1995, Kraft's confectionery business (including Jet-Puffed Marshmallows) was sold to Texas Pacific Group, which formed the company Favorite Brands International.

Kraft at one time offered a replica of the marshmallow dispenser that Spock used in the movie Star Trek V: The Final Frontier.
