TV, or in this case, YouTube can be an excellent way to learn about many things. I really like that IBM is taking an active role at getting valuable content out on YouTube. What's even better is that many of the videos become viral and end up getting many views.
The videos are extemely well done and worthy of going viral. Take these two videos: Servers for Truth #1 and Servers for Truth #2. The videos are in answer to several claims made recently by Oracle. You'll enjoy... and get the REAL story!
Another set of videos that you may wish to watch on YouTube are the "Let's Build a Smarter Planet" series. Again this is a set of amazing videos that explain how and why the world needs to be smarter. My favourite is the one where Jeff Jonas is the star... which one is it? Watch them all to find out.... you won't be disappointed!
