Previously two companies, fixed-line operator Český Telecom and mobile operator Eurotel, it was acquired by the Spanish company Telefónica in 2005 and merged into a single legal entity and given its present name on 1 July 2006. In 2013 it was announced that Telefónica would sell its stake in the company to PPF and the company would continue to use the O2 brand for a maximum of four years. In August 2017 the brand license agreement was extended to 2022, with a 5 year extension to 2027 available. History The company was initially known as SPT Telecom (Státní telekomunikační podnik, state-owned telecommunications company), and used to have a monopoly for providing fixed-line services. It was reorganized and renamed Český Telecom (Czech Telecom), after the Velvet Divorce saw Czechoslovakia separate into the Czech Republic and Slovakia in 1993. Its mobile subsidiary, Eurotel, was founded in 1990 as a joint venture between SPT (51%) and the American joint-venture Atlantic West (between US WEST International, Inc. and Bell Atlantic International Inc.). On launch, it received an exclusive five-year licence to operate a public data network, and a 20-year licence for the 450 MHz band to operate an analogue NMT mobile phone network, and automatically also a right to buy a licence to the future GSM network. In 2001, it won a license to the third-generation UMTS network. It paid 1 billion korunas immediately and promised to pay an additional 2.5 billion korunas annually. It also agreed to launch the service commercially, at least in Prague, by 1 January 2005. In 2003, it received a one-year extension in exchange for faster payments. In 2005 it was granted another year-long extension due to the granting of a third licence to Vodafone. In the event, UMTS services launched on 1 November 2005. On 1 May 2006, the company launched HSDPA services on top of UMTS services. In 2004 it launched CDMA/1xEV-DO broadband wireless service (data-only) at 450
