'Media & Technology iQ’ has identified Berlin as the biggest threat, with five new start-ups created in the German capital every day. A recent study suggested that, by 2020, Berlin could add more than 100,000 new jobs thanks to start-ups. Key players in the tech market like Amazon, Microsoft and Zalando continue to be attracted to Berlin for its low-cost office and living space, ‘trendy’ image, central location and simplified immigration policy for skilled workers, drawing even more investment and talent to the city.

As the economy rebounds, Dublin is set to consolidate its top three position through exposure to large tech players and the data centre industry. With landmark lettings to Facebook, Amazon and Yahoo, the IT sector represented 30 per cent of office take up in 2013. Specifically US tech giants invested over $130 billion into Ireland between 2008 and 2012, almost as much as they invested in all of developing Asia. However, the emerging shortage of ‘quirky’ Grade-A stock, growing rental levels, changes to the US tax regime and the planned increase in Ireland’s corporation tax rate  (currently at 12.5 per cent) are likely to impact on Dublin’s pace of growth and competiveness.

Craig Satchwell, Head of EMEA Office at Colliers International said: “London is still going strong - over 46 per cent of 2013 leases in the West End attributed to tech and media companies - and ‘Tech City’ continues establish its dominance. However, if London is going to remain at the top, landlords and developers need to urgently address the shortage of central, quality stock and increase provision of flexible and innovative space. Coupled with the fact that Dublin, Berlin and the Nordics are offering businesses young and fresh talent in abundance, London needs to address the increasing skill shortage in the UK to maintain its crown.”

Bruno Berretta, Senior Research Analyst and author of Colliers International’s Media and Technology iQ, said, “The media and technology sector is now the most important and active business sector and one of the key economic drivers in a number of European markets. The tech landscape has developed significantly over the past few years. Not only are ‘rising stars’ like Berlin and Dublin claiming considerable market share from London, but also ambitious Nordic cities like Stockholm and Helsinki and Central Eastern markets in Poland, Slovakia and Hungary are emerging as strong regional hubs.”
