In addition to the economic activities that come with being the national capital, Ottawa is an important technology centre; in 2015, its 1800 companies employed approximately 63,400 people. The concentration of companies in this industry earned the city the nickname of "Silicon Valley North". Most of these companies specialize in telecommunications, software development and environmental technology. Large technology companies such as Nortel, Corel, Mitel, Cognos, Halogen Software, Shopify and JDS Uniphase were founded in the city. Ottawa also has regional locations for Nokia, 3M, Adobe Systems, Bell Canada, IBM and Hewlett-Packard. Many of the telecommunications and new technology are in the western part of the city (formerly Kanata). The "tech sector" was doing particularly well in 2015/2016.
