There are billions of hours of video on YouTube. Literally. And that’s hardly the most astounding statistic about the site, which has been the go-to destination for uploading and watching video since 2005. That said, sometimes, you really want or need to have one of those videos on your own computer or phone. But when the topic of downloading YouTube videos comes up, there’s a side subject that must be broached: Is it legal?
[CognitiveMetropolis] Here’s a clue: How did you get the YouTube video in the first place? Did a little bird fly it through your window on a Blu-Ray disk for you? No… You downloaded it. So, yeah, its legal to download it. Can you keep it for yourself on your hard drive for all time and eternity? You know what they say, “possession is 9/10s of the law.” Here is a question for you: is there a copyright law that says you can only utilize or view copyrighted material in non-persistent RAM-based storage for limited amounts of time not to exceed the length of playback? I bet not. Go get your videos.
