We received our first TV in 1952, I was 10 at the time. After 5pm the TV was the domain of the parents and what they wanted was what was watched. The Lineup was one of my dad's favorite shows and mom loved Arthur Godfrey (UGH!).
In spite of all the broo-hah about Dragnet and Joe Friday at the time I thought the Lineup had superior acting to Dragnet; much of the dialog being monotone and obviously not scripted well.
I liked the original theme song when it was a ZIV production; DesiLu reorchestrated and ruined it.
