Imagine a whole generation of kids growing up and learning about the world through YouTube. In the first half of the 20th century, people grew up reading books and newspapers. Then there was a generation that grew up on movies and television. The last shift was to the Internet. And now web video is creating yet another generation. Kids no longer learn about the world by reading text. Like the television generation, they are absorbing the world through their visual sense. But there is a big difference. Television was programmed and inflexible. YouTube is completely micro-chunked and on demand. Kids can search for what they need anytime. This is different, and powerful.
