This was a sales gimmick from the very beginning (see my post from November when Monty Python launched the channel) and, apparently (LOL!) it has been an earth-shattering success! Monty Python is now sitting pretty in the #2 slot on Amazon.com for TV and movies, and as Mashable notes that's likely because of all of the links embedded in the YouTube clips that take viewers to the appropriate product page at the Amazon site.
The lesson from this should not be lost on those from the RIAA, and others who have been overly-zealous in enforcing "copyright" on the flimsiest of grounds. This story demonstrates more than adequately that YouTube can be a marketing powerhouse and that it is a friend to commercial art, not a foe to be shunned.
(Thanks to Phillip Arthur for passing along the story!)
