For anyone who would like to legally buy Carl Sagan‘s series Cosmos so you can watch it when you drive or work out or are sitting in class, all the episodes are now available on iTunes!

The whole series is $25.87 while individual episodes are $1.99. (In other words, there’s no discount for buying all of them.)
For those of you who have never considered that the words “iTunes” and “legal” could be in the same sentence, I’m sure you can download/watch the excellent series for free somewhere on the Internets… but I can’t find it anywhere.
