2018 marked the 40th anniversary of the premiere of Dallas, the CBS prime time soap opera that ran for 14 seasons, including the second-most watched series episode in U.S. broadcast history (the cliffhanger-solving Who Done It?, with at least 90 million viewers), and gave television its hands-down greatest villain: actor Larry Hagman’s J.R. Ewing, the evil, scheming, downright degenerate Texas oilman who captivated the imaginations of America’s last unified TV viewing audience.
