YouSee (TDC), Denmark's largest quadruple play service provider, was established as a result of a long evolution in the country's telecommunications sector. The company's origins can be traced back to 1963 when Jydsk Telefon, a regional telephone company, first showed interest in cable television. However, it was not until 1985 that the Danish Parliament (Folketing) allowed regional companies to develop a nationwide cable TV infrastructure. In 1990, a new law enabled the creation of a nationwide Danish telecom, Tele Danmark, which became the parent company for existing regional companies. By 1995, these regional companies had merged into Tele Danmark, and the first nationwide cable TV company, Tele Danmark Kabel TV, was created. In 2000, Tele Danmark rebranded as TDC, and Tele Danmark Kabel TV became TDC Kabel TV. This was subsequently renamed to YouSee in 2007. In 2016, TDC's consumer business was merged with YouSee, transferring all of TDC's IPTV, broadband, and mobile consumers to YouSee. In 2018, TDC Group divided its business into two units, NetCo and OpCo, with YouSee being moved to OpCo, which focused on digital services and customer experiences. OpCo was later renamed Nuuday in March 2019, and by June 2019, Nuuday was legally separated from TDC NetCo to function as its own subsidiary of TDC Group.

The company has provided 2G GSM services over the 900 and 1800 MHz bands since July 1992, and 3G UMTS services over the B1 (2100 MHz) band since May 2007. The network was upgraded to support HSPA+ in May 2010, and DC-HSPA+ in March 2011. An additional B8 (900 MHz) service was launched in 2014. The network was shutdown in 2022.

    4G LTE was commercially launched in October 2011, initially over the B7 (2600 MHz) band, and later B20 (800 MHz) in early 2013. July 2015 saw the activation of LTE-A, with the network advertising peak data rates of 300 Mbps using 2C carrier aggregation (B7+B20). The network was upgraded to 3C CA, adding an additional B3 (1800 MHz) service to the mix.

    4.5G LTE-A Pro was demonstrated December 2016 ahead of its early 2017 launch, where the network exceeded 1 Gbps using 4X4 MIMO and 256QAM.

    TDC has been trialling NB-IoT since early 2017, and announced in February 2018 that it was in the process of deploying the service nationwide over a 200 kHz channel in its B20 (800 MHz) guardband.
