We have basic cable, basic being about 10 channels and we rarely rent movies. So I was quite pleased to discover Hulu. They have full length movies, episodes of various shows and clips from other shows. They stream them to your computer in short segments so you will need a high speed internet connection. A whole lot of what they I have I can certainly live the rest of my lifetime without ever viewing but they have some things that I'm happy to be able to see. The movies do have commercials but they seem to be shorter than those on TV. Over vacation I watched A River Runs Through It and there was only one small section where the feed seemed to bunch up.
You can also use the embed feature to place things on your blog. I think this is quite funny. Enjoy!
