Black Friday refers to April 15, 2011 when major poker sites were shut down in the U.S.
Explanation. The U.S. Department of Justice indicted executives of major online poker sites (e.g. PokerStars, Full Tilt), freezing operations for U.S. players. Nicknamed “Black Friday,” the day radically changed online poker legality. It forced many players off U.S. platforms, reshaping the industry forever.
