Today is an important day in #pinball history: 90 years ago, pinball operation was banned in the City of Chicago.
The "Prohibition against Bagatelle or Pigeonhole Games" was maintained until 1977, even as the pinball companies continued to build their machines there.
I discovered the precise date of the ban, though some years ago Ryan Zickgraf of the Chicago Reader made a noble effort to determine when it occured.

I'm still searching for the exact date of LA's pinball ban.
