Nick Baker’s collection of programmes and interviews reflects on how the impact of technology has changed, from the dawn of language to the age of virtual reality.

In this episode, Software, Nick revisits two of the past music software formats that used to dominate. In The Curse of the Cassette [from 1997], he recalls the downside of a much reviled format. Then, in the AB of CD [from 1988] Simon Bates looks at what the then revolutionary medium would bring to pop music.

Nick also meets Simon Rooks from the BBC archives.
