The Book of the series, The Ascent of Man: A Personal View by J. Bronowski, is an almost word-for-word transcript from the original television episodes, diverging from Bronowski's original narration only where the lack of images might make its meaning unclear.
Less than a year after the series appeared on BBC TWO, Bronowski died. Some claimed that the stress of working on the series had proved too much for him.
In the late 1990s Douglas Adams recorded new introductions and afterwords for a rerun of the series on the British satellite channel UK Horizons. Although billed as the first complete rerun of the series in more than a decade this was not true because the episodes were cut by up to five minutes to make room for commercials and the new material. In fact the complete series has not been screened uncut in Britain since 1986, and seems to only be available from several suppliers - including Ambrose Video Publishing (video or DVD) and Documentary-Video (video or DVD) - for delivery within the United States only.
