Sonofon and Cybercity merged in 2006 to form an alliance. On 15 June 2009, the two brands merged and renamed to Telenor.



Cybercity has initiated a tight cooperation with Sonofon, sharing headquarters on Frederikskaj in Copenhagen (where Sonofon's main administrative sections are housed), and even going as far as using Sonofon-hired and trained consultants within Sonofon's main call centre as a secondary base of customer service operations.


In May, 2007, Telenor announced the purchase of competing ISP Tele2,[1] with the Danish commission of monopoly approving the purchase (later the approval was announced to the press, currently the main press release).[2]


Cybercity was a name of a leading Danish internet service provider owned by Telenor. The company has its own nationwide core network, and serves both consumer and business customers. Cybercity has reported more than 186.000 DSL customers in its report for the first quarter of 2007[3] (Danish), with more than 380 employees.
