Since 2008 we’ve been covering the gradual emergence of a cluster of technology startups in East London. Hell, we’ve even made films about so-called Silicon Roundabout. But it wasn’t until the Prime Minister suddenly appeared in the area to declare it a focus for government policy that larger tech companies started to take notice of what some random policy advisor decided to brand “Tech City“. Since then there has been a litany of pledges pledged by corporates like Cisco, BT and Facebook to keep Number 10 Downing Street happy, but not a huge amount of, well, action. All that changes today with the news that Google is to rent, lock stock and barrel, for the next ten years, an entire seven-floor building in the area.
