Gaping Void has some interesting observations on how the world of advertising is changing: "The future of advertising is clients increasingly asking their agencies to help re-invent not just their brands, but their actual companies. The future is agencies being increasingly unable to deliver on this. Out of this wreckage a new industry will emerge..."

Interestingly, the same dynamic appears to be at work in the PR industry, says David Parmet: "There's a similar model in the PR world. We're the gatekeepers between the media and the body corporate. But with blogging it's becoming increasingly impossible to tell where one starts and the other ends... Clients want the results - the media hits from us, the ads from you - not talk. Suits are incapable of giving them results."
