There's a significant shift taking place in the world of advertising, media and communications, and it's time for media professionals to wake up.
Some of the core elements of the change involve ownership and delivery of multimedia messages. It's one of the reasons why the RIAA fights music sharing, and why advertising revenue, particularly for mass media such as television and newspapers, declines despite the outlets' reinvention efforts.
Terry Heaton has an excellent article on the topic, which I encourage you to read.
Between TiVo (which I *love*) and other changes in the works (Google video rentals?, TV shows for your iPod), the world is a changing, and it's going to be one of the biggest shifts since the era of modern media. I'm excited to be a part of it, and can't wait to see what happens.
