The game itself is believed to have evolved from older guessing games, perhaps even dating back to ancient times. However, the modern version with a set number of questions (20) and specific rules likely emerged in the late 19th or early 20th century.
Here's a breakdown of its likely origins:
* Ancient Roots: Simple guessing games where players try to identify a hidden object or person existed long before the "20 questions" format.
* 19th-Century Popularity: The game likely gained significant popularity in the late 19th century, possibly coinciding with the rise of parlor games and social gatherings.
* Formalization: The specific "20 questions" rules, including the limitation of 20 questions and the categories of people, places, and things, probably became standardized around the early 20th century.
* Radio Show: The game was further popularized by the 1940s radio show "Twenty Questions," which helped solidify its name and rules.
So, while there isn't a definitive origin story, it's safe to say that the idiom "20 questions" evolved over time from older guessing games and solidified its meaning through its association with the popular game.
