The seeds of huge marketing changes are being planted now. In hindsight, historians will see that a revolution occurred. But to us in the know, it will only appear to be an evolution while to the digital natives it will just be inevitable.
So don't think of it as a revolution - people and especially clients don't like revolutions. Don't expect it to be broadcast - people and especially clients will be unaware of it (or, at best, sceptical). Just know that you are ahead of the game and that people and especially clients will be hugely impressed by your foresight.
