There have been two incarnations of the television show "Dallas," the first being a prime time soap opera that followed the Ewing family and their feuding, while the second version followed the younger generations as the feuds over the family business and family drama continued. The first version ran from 1978 to 1991, while the newer show only ran from 2012 to 2014.
The show originally focused on Bobby Ewing and Pamela Barnes, whose families were enemies. The show shifted a bit when Bobby's brother J.R. Ewing became the focus, along with his dirty business dealings and family drama. This show has the second most viewed episode in primetime television history with the "Who Done It" episode after J.R. was shot.
