The "Dallas" TV series was a huge success in the 1970's.
On March 13, 1980, the season ended with someone shooting JR Ewing, the character that everybody loved to hate.
The show's fans, and a few others spent most of the summer wondering "Who shot JR"?
On this day in 1980, millions of people around the world tuned in to answer the question: Who shot JR?
83 million people in the country saw the show or an amazing 76% of all of the TVs in the US.
As I recall, it was Kristin who shot him!
