In addition to longtime functions as seaport and capital city, Tallinn has seen development of an information technology sector; in its 13 December 2005, edition, ''The New York Times'' characterised Estonia as "a sort of Silicon Valley on the Baltic Sea". One of Tallinn's sister cities is the Silicon Valley town of Los Gatos, California. Skype is one of the best-known of several Estonian start-ups originating from Tallinn. Many start-ups originated from the Soviet-era Institute of Cybernetics. In recent years, Tallinn has gradually been becoming one of the main IT centres of Europe, with the Cooperative Cyber Defence Centre of Excellence (CCD COE) of NATO, the EU Agency for large-scale IT systems and the IT development centres of large corporations, such as TeliaSonera and Kuehne + Nagel being based in the city. Smaller start-up incubators like Garage48 and Game Founders have helped to provide support to teams from Estonia and around the world looking for support, development and networking opportunities.
