How our ambitions change as we grow up. When Google was little it wanted to be a technology company that did no evil. Then it decided to be an internet media company, bought YouTube, and did deals with AOL and MySpace. Now, with its purchase of Doubleclick, it seems Google wants to be a slick advertising agency. That deal has given rise to competition concerns - which are largely misplaced - but Google is in need of some careers advice.
Google plans to acquire the oddly named Doubleclick - most web adverts land you in an online casino with one or sometimes zero clicks - for $3.1bn. Doubleclick specialises in animated "display" ads rather than the text-based "search" ads that are Google's bread and butter.
