Flying disc history: Identify the year the Frisbee game/disc was introduced commercially. Full question: When was the game Frisbee invented (commercial plastic disc popularization)? Choose the correct option.

Given data

• Term: Frisbee (branded plastic flying disc).

Concept / Approach Students tossed pie tins earlier, but the modern plastic disc took off when Wham-O marketed Walter Morrison's "Pluto Platter" and then branded it as the Frisbee in 1957.

Option analysis 1957 — Correct; Wham-O's branded launch. 1948 — Morrison's early plastic prototypes (pre-Wham-O branding). 1966/1973 — Later milestones in disc sports, not the original commercial launch.

Common pitfalls Confusing informal pie-tin tossing dates with the branded Frisbee product introduction.

Final Answer 1957.
