Can you hear the theme music? We are entering TV's "Twilight Zone," where families will no longer huddle together around a glowing box in the living room during "prime time," where programming will be 24/7, portable, on-demand and limitless, where everything is about to change.

We live in a parallel universe where the PC/Internet world is separate from the TV/broadcast world, but their future is inexorably intertwined. All movies and all music will eventually be distributed via the Internet. The CD, CD player, DVD and DVD player all have a use-by date on them. TV broadcasting and its associated business models have not changed significantly over the last 50 years, but digital technology will ensure that TV over the next 50 years will undergo a massive change, the form of which will be governed by the consumer.
