An anonymous reader writes "Apparently it with the release of all of Monty Python's material on YouTube, their sales have blown through the roof on Amazon.com. It is too bad there isn't any proper news article about this, but I think it bodes well for those who champion free content. More importantly, it forces the MPAA's feet into their mouths."
Not every performer (or group of performers) has the decades-strong appeal of Monty Python, but this is a great thing to see. The linked article claims that the sales increase in the Python DVDs is 23,000 percent; there are probably some other ways to figure the numbers, but a big increase is easy to see.
