Don't we all love to watch a great video...

Does anyone remember the days before instant access to videos. I do. I remember the days before SMARTboards and computers in the classroom and when if the teacher wanted to show us a movie, they had to place an order for the TV and VCR (wow! I just dated myself!) and then we would watch the movie.  Now, students only know of YouTube and DVDs and being able to pause simply by a touch. If a teacher wants to show students something, no longer do we need the request of a DVD or VHS or TV--SMARTboards have eliminated the need for that. I have such a mix of feelings towards this change that I can't come to a conclusion on whether or not I like it. I love the fact that I can show students videos about things ranging from the Mayflower to letter sounds to what animals look like in their natural habitats.  I love that I can show students a reading or animated version of a book that we have read and they can see different interpretations of things as well as expand their imagination.  However, I really dislike the fact that students now only know of instant videos and the ads that appear on the sides of EVERYTHING. Students would rather watch video of a book rather than listen to or Gd forbid read the book. Ads are very often inappropriate to show students, other videos listen on the sides distract students, and then there is always "I can't see!!!" Or "I can't hear!!!"
I love the positives, and there may be more of them, but the negatives seem to be worse.
