I primarily use Youtube for entertainment purposes, however, I find it very useful to increase my knowledge on different topics from cinema releases, comedy to random uploads which become the perfect time wasting exercise. I love the comedy aspect of Youtube and the fact it is an available platform for anyone who wants an immediate audience. It's great for e-learning as you can find literally anything you want. It creates general online discussions and it encourages the sharing of ideas. I occasionally watch top 10 lists of interest from sport to video gaming to movies which makes Youtube a great sharer of popular culture. It is also extremely useful when viewing film trailers to gauge whether to watch the film with the extra helpful comments and reviews.
Generally, I don't use iTunes at all which means that I have no experience with iTunes' and their trailer presentations.
