What Was Google's Naughty Little Secret?
Let’s be honest, the inner workings of digital advertising are about as thrilling as watching paint dry. But the concept behind the EU’s complaint is surprisingly simple. Imagine you’re at a property auction. The auctioneer not only runs the bidding but also owns the estate agency selling the house, represents the wealthiest buyer in the room, and has written the rules to favour that buyer. Would you feel you had a fair shot? Of course not.
That, in a nutshell, is what Google was doing. It controlled the entire supply chain. It ran the ad exchange where digital ad space is sold, it owned the tools advertisers used to buy that space, and it owned the tools publishers used to sell it. By systematically favouring its own services, a practice regulators call "self-preferencing", Google ensured the house always won, because it owned the house, the tables, and all the chips.
