I was invited to a meeting a few months ago which included reps from Phorm, the behavioral targeting ad network who are currently attracting a lot of controversy from internet rights groups. The bad press is down to the novel - and slightly unsettling way - Phorm dips into your browsing history in order to be able to target ads at you on sites which are part of its affiliate network.
It does this not by looking at your browser history, but at the records kept at your ISP, which it then turns into a cookie in your browser.
Most people I know would be alarmed at this basic form of snooping, however benign the intention. There are questions to be asked of ISPs too, who have quietly consented to this invasion of privacy, simply for a cut of the ad dollars.
Not quite so voluble, but no less concerned, are the publishers. Phorm's system takes away an aspect of the premium attached to the site/brand sell for advertising. Phorm's ad network can track users of target sites and deliver ads to them specifically from anywhere else. You want visitors to FT.COM who have also visited moneysupermarket, comparethemarket and Autotrader in the last 30 days (we can safely say they're looking for insurance for a new high end car)- Phorm can do it.
The last kick in the groin is that Phorm's marketplace is a dutch auction, so publisher's are encouraged to drop the price they are willing to accept in order to get the business from advertisers, who put a maximum delivery price on their campaigns. There is only one way this model will play out - 'beggar my neighbour' between publisher scrabbling for ad revenue to fill their excess inventory.
Phorm of course realise they need affiliates to actually serve the ads, so they soft-peddle the harsh reality of this kind of market, and they also know that smaller players without an ad salesforce will see revenue they otherwise could not get. Large publishers will effectively subsidise them by providing the demographic of the 'premium' audience who go to them en masse, and are then targeted somewhere in the realms of the blogosphere or on some minor site.
Will Phorm's product take off? Does it matter if large publishers stay out - assuming they choose to do so? Has the time of the ad auction arrived? Will negative publicity cause the ISPs to chicken out? Could the Data Protection Act play a role?
All these questions and more will be answered in the developing episodes of the soap opera.
