YouTube is a phenomenon unto itself and possibly the most
successful product for Google after Google search. Launched back in November
2005, the website attracts more than 1 billion unique users every month, and
more than 6 billion hours of video are watched during the same period.
Although it might be
frowned upon, there are many legitimate reasons to download a YouTube video.
One is when you've recorded a video, uploaded it to YouTube, and then lost the
original copy. And then there are copyright-free works to consider — from open source
and creative content videos to those available in the public domain. You might
not even be interested in the video and may just want to download its audio (or
soundtrack) instead.
