Who shot JR? In 1980 at the end of series six, Dallas came up with arguably the greatest end of season cliff-hanger ever. JR was pictured being shot three times – then viewers had to wait all summer to find out not only if he survived, but whodunit? It was estimated that 83million people tuned in the following November to find out which of JR's enemies was responsible. (It was Kristin, his sister-in-law and mistress and yes, of course he survived.)
