Black Tuesday

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Black Tuesday refers to a number of different things:

  • The phrase Black Tuesday also refers to September 29, 1931 when Estevan miners protesting were fired upon by RCMP officers.
  • Black Tuesday has also come into use as a reference to the day Microsoft releases bundles of patches for its Windows operating systems: the second Tuesday of each month. These patches represent new software vulnerabilities, and the bulk release of patches is often followed closely by new viruses which exploit the holes the patches fix. See Patch Tuesday.
  • Black Tuesday can also refer to November 29, 1939, the date of the climax of a period of extreme smoke cover in downtown St. Louis, Missouri. The pollution was due primarily to the widespread use of bituminous coal, and resulted in near zero visibility and the use of streetlights at midday.
