It was quite some time before more advanced editing techniques made

Not quite sure what you mean by this, presumably you are referring to
the advent of electronic editing.

What was it that precluded electronic editing by dubbing from one tape to
another, as they did until a few years ago? Was it simply that copying from
one tape to another in the early days brought the quality below acceptible
broadcast standards?
