Something I find super interesting about 20th century scripted dramas from the UK and USA is how short the turnaround from filming to broadcast. An episode of Star Trek The Next Generation (1986) was sometimes filmed only a month before broadcast. The final episode of Survivors (1975) season 1 was filmed five days before broadcast. Hair-raising. In Australia they were shown months or even years later so I guess in my head they had this prestige of sitting on a shelf
