During the
1969-70 broadcast season, NBC aired what I gather was a semi-anthology series called
Bracken's World in the 10-11pm timeslot on Friday nights. That series remained in that timeslot during the first half of the
1970-71 broadcast season, after which it was cancelled and replaced by a British import called
Strange Report, which only lasted 16 episodes. (Honest question -- did any of the ITC imports to the United States in the 1960s last on American network television?)
Secret Agent and The Saint had good runs. Strange Report is an odd one. It was produced in England for ITC by Arena Productions, which had made The Man from UNCLE and Dr Kildare. The plan was for the series to continue after the first 16 episodes, but relocate along with two of its lead actors, Anthony Quayle and Anneke Wills, to the US. The actors didn't go for that idea, so the show ended early. Shame.
