Advertising is a $600B a year business, and the Internet still has yet to catch up with other media in terms of share of total budget versus time spent on the medium. Google just reported revenues up 35%. It's all advertising, driven by high quality algorithms and lots of data. Internet advertising is more effective than other media and we're still just scratching the surface. I'd like to comment on all the specific…
I hear a radio ad. It is interesting. I write down the number and call the person. Not ideal, but I am reminded by the medium that I must act now or else I lose the info of the ad. Same with tv ads. But even to ensure people can follow up you have to have the ad repeated over and over.
With print ads, I can cut them out and save them. Less urgency, and a lot of durability.
Online advertising, with the possible exception of advertising on search engines, provides the illusion of durability without delivering it. So it's an inferior medium.
I am not saying that online advertisements are doomed. I think we haven't figured out how to do it, and borrowing print analogies isn't sufficient. Or perhaps, if we are going to borrow print analogies we ought to take them all the way (selling ad space on specific pages on a non-rotating basis for example).
