LONDON, ENGLAND - MARCH 15: People work at computers in TechHub, an office space for technology start-up entrepreneurs, near 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. Entrepreneurs using TechHub are predominantly product-oriented tech companies who rent desk space and use the fast wifi. 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.
