What's the internet for?
I don't see it as a marketing channel, and I've never seen the evidence to support the view that it succeeds as such. You might argue that Google Ads proves me wrong, but the reality is summed up in the comment that Seth Godin makes with reference to Twitter. He says that Twitter isn't a marketing medium, it's a "connecting medium".This is true of the Internet as a whole - if we just view the Internet as cheaper television we'll have failed completely.
