If you want this because you think you enjoyed it on PBS, it's important to know that PBS has broadcast at least two similarly-named 10-hour series on the topic of rock music history. One, titled "Rock and Roll" by "The Experience Project", as I recall, is relatively "deep" and I gained some appreciation of
even topics in which I had little interest (e.g. punk rock).
The other series, "The History Of Rock And Roll", by Time-Life (now Time-Warner), which appears to be what you see here, is enjoyable but shallow, and I was annoyed that the live performance clips are very short (don't expect to see a complete song).
Both series were produced several years ago, and unless this series has been updated it has no coverage of recent music.
If you could only afford one series, I would normally recommend "Rock And Roll", not this one. However, PBS seems to have a monopoly on "Rock And Roll", and last time I checked they would sell it only to educators, not the general public.
At $100 for 10 hours, this is also not a particularly good
value. The price per hour is nearly 3 times the price of, for
example, a year's worth of M*A*S*H episodes (24 episodes,
each with 22 non-commercial minutes, for about $35).
Thus, this series is not the best on the topic, and it's
not the best value for your DVD dollar. I did enjoy the
series, however, and if you are fortunate enough to be
able to fit this into your budget, I do recommend it. I
am ordering a copy for myself.

seeing the series on PBS. The DVDs have not yet been
released yet and I have not seen them.
