LONDON, ENGLAND - MARCH 15:  Employees work at computers in the office of 'Content and Code' on the Old Street roundabout in Shoreditch which has been dubbed 'Silicon Roundabout' due to the number of technology companies operating from the area on March 15, 2011 in London, England. Content and Code are a technology consultancy company and Microsoft partner. The relatively low rental rates and proximity to media and internet companies has made the area close to the roundabout a prime location for IT firms and web entrepreneurs.
