I didn't watch Cosmos when it was on since I was too young, so I got introduced to this not that super long ago. Somewhere around 2010 is when I first saw and then read the book, but now I finally listened to the audiobook - it's just as great. A lot is the same as the series, but there are some differences that do not take away from anything. Levar Burton is great as the narrator, although admittedly, not that it would have been possible since the audio version is very new, I did kept expecting to hear Carl Sagan's distinctive voice when I started it. ;)
