Google’s engineers are readying YouTube to go after another billion viewers in Asia. That might not sound like much, but from a marketing perspective, it is breathtaking. Companies that serve a billion or more people are but a handful, yet Silicon Valley thinks in these huge numbers regularly. It is no accident that media, such as YouTube and Facebook, are the vehicles reaching such large numbers. Communications are at the core of human experience. And, both media make room for individual contributions to the conversation whether it is cat videos or celebrations of someone’s birthday. They encompass a universe of interests from which marketers and PR practitioners can segment those they want to reach. Social media have become the well from which the rest of the world draws.
