Dallas

 April 2, 1978, Dallas premiered on CBS.

The series centered on the wealthy and feuding Ewing family, whose oil empire Ewing Oil and Southfork Ranch became the backdrop for decades of scheming, betrayal, and power struggles. The show originally focused on the marriage of Bobby Ewing and Pamela Barnes, but later shifted heavily toward the ruthless machinations of J.R. Ewing, played by Larry Hagman. The ensemble also included Barbara Bel Geddes as Miss Ellie and Jim Davis as Jock Ewing.

The series aired from April 2, 1978 to May 3, 1991, spanning 14 seasons and 357 episodes, and became a cultural phenomenon thanks to legendary cliffhangers like “Who shot J.R.?” and the famous “dream season” twist. It also launched the successful spin-off Knots Landing, expanding the Ewing universe across primetime television.
