They will enable families from far-flung regions to better stay in touch. Viewers can look at cities around the world to see local weather and watch live special events. Imagine if you could have seen a live Webcam of your young relative's first day at school from your computer at work. And many immigrants would love to view images of their homeland at any time. These are now all generally available.
Cameras can also be a great learning tool.
Imagine having a camera set up so students can get a live, but safe, view of a volcano erupting. Hollywood would have nothing better to offer. Webcams will turn the broadcasting industry on its ear. With a broad range of choices, you can watch whatever you want. Webcams can also be used to ensure that your child is being treated well while at the babysitter's, or to look in on your dog at home to make sure he isn't on the couch.
