text: Dallas is an American prime time television soap opera that aired on CBS from April 2, 1978, to May 3, 1991. The series revolved around an affluent and feuding Texas family, the Ewings, who owned the independent oil company Ewing Oil and the cattle-ranching land of Southfork. The series originally focused on the marriage of Bobby Ewing and Pamela Barnes, whose families were sworn enemies. As the series progressed, Bobby's elder brother, oil tycoon J.R. Ewing, became the show's breakout character, whose schemes and dirty business became the show's trademark. When the show ended on May 3, 1991, J.R. was the only character to have appeared in every episode.
