The future of advertising is to stop trying to advertise to people, and instead start participating in the stream that people want to use. People will follow your brands if you contribute to whatever it is the people are up to.
This is a modified version of a statement Stowe Boyd made recently in a post. He was talking about the future of advertising on mobile but I feel it applies everywhere now.
In fact it nails it.
Stop advertising. Start participating and contributing.
