On November 21, 1980, 350 million people around the world
tuned in to television’s popular primetime drama “Dallas” to
find out who shot J.R. Ewing, the character fans loved to hate.
J.R. had been shot on the season-ending episode the previous
March 21, which now stands as one of television’s most famous cliffhangers.

The plot twist inspired widespread media coverage and left
America wondering “Who shot J.R.?” for the next eight
months.

The November 21 episode solved the mystery, identifying Kristin Shepard, J.R.’s wife’s sister-in-law and his former mistress, as
the culprit.
