My guess would be that PBS can’t/doesn’t want to pay for all tha bandwidth it would take to stream all of their docs. That’s really a lot.
That’s why a site like Megavideo limits the amount of time each user can watch continuously so one typically has less than a full program before it stops. They can then come back in 2–3 hrs. to resume watching. This enables them to manage the bandwidth allocation.
I also noticed that both of these sites state in their FAQS that they are not the hosts of the files but merely provide a link to a site which does host the content on their servers.
I also noticed that one of the sites hosting the files for GG&S is Google. That makes sense to me.
Both sites (and perhaps Google also) provide a link for you to purchase the series.
I know that ever since the YouTube fracas, Google will promptly remove any content which the owner of the content objects to.
If PBS did not want these files available on Google, I’m quite sure they would have notified them by now :)
Since streaming is different from downloading, it’s a symbiotic type of arrangement. PBS gets free exposure for old Docs, (and possibly some DVD sales) without incurring hosting costs and Google gets the site traffic and ad revenues.
That’s my best guess. I could be totally wrong but my hunch is I’m not far off the mark :)
PS
I agree with you that just watching the vids is no substitute for the book. The history of civilization can hardly be summed up in 3 hrs. It would be unwise to leave off reading the book in addition.
The video version hits the major points but leaves one with lots of Qs as to how Diamond came to the conclusions he did.
I didn’t know about the book prior to watching the program in its initial airing. But I’m kind of glad for that since it provided a good basic “road map” for the book and made tackling the book less drier.
So I agree that one will gain significant insights from the book.
