The hit CBS series *Dallas*, which debuted in 1978, told the story of the wealthy and powerful Ewing family, whose business and personal lives were defined by corruption, rivalry, and betrayal. But it was J.R. Ewing, played by Larry Hagman, who quickly emerged as the show’s standout character. A ruthless oil tycoon, J.R.'s scheming and backstabbing made him one of the most memorable villains on television, earning him a loyal following.

### A Cultural Moment
The phrase “Who Shot J.R.?” became an international phenomenon, appearing on merchandise and even influencing political campaigns. Rumor has it that during the 1980 U.S. presidential election, Ronald Reagan's team worried that the episode’s timing could affect voter turnout, with some fearing more Americans would stay home to find out who shot J.R. rather than head to the polls.
“J.R. Ewing became larger than life,” recalls Larry Hagman, who played the character. “People didn’t just tune in to see what he’d do next—they couldn’t get enough of him. It was the perfect storm of a character and a storyline that just hit at the right time.”
