According to the Intel’s Chief of Labs, Justin Rattner:
You can imagine 15 billion consumer devices that will be capable of delivering TV content in that timeframe with 100’s of billions of hours of video. We’ll need much more sophisticated ways to organize content and provide it on demand.
Based on the tons of statistics about YouTube, Hulu, etc, we can safely say that video and TV represent just another type of information overload. And considering the video usability current state the problem will be much more difficult to solve. But I do expect to see huge innovations in the field.
