When this weekly 50-minute British adventure series debuted in 1965, it went out under the title Mogul. Created by John Elliot, the series chronicled the exploits of a major oil company, from the executives on down to the riggers. After 13 episodes, the title was changed to The Troubleshooters, which it remained for the next 123 installments. The series continued wending its successful way through the BBC1 distribution channels until 1972. ~ Hal Erickson, Rovi
