For the full effect of this blog post, watch the video, and count the number passes that the team in the white uniforms makes.
I often tell people about how consumers have more and more technology available to them to block out advertising. TiVo/DVR. Satellite Radio. Caller ID. Do Not Call lists. Spam blockers. Etc.
But the best technology available is the human brain. When we focus on a task like reading a web page, we naturally tune out eveythting else. For instance, right now you are reading the text of this article. You are not looking at the orange block ad to the right.
So, if you are a marketer, don't you want to be the one publishing the content, not buying the ads? Sounds like you should start a blog, or publish videos on YouTube or give webinars (not demos, but informational webinars your prospects will find remarkable).
I found this video on Seth Godin's blog. If you don't read it, you should.
