Designer:  Lambie-Nairn
Typography:  Frutiger
Launched:  Unknown

In 2001, BT Wireless demerged from BT and took the name mmO2 plc. While mmO2 plc was created in 2001, the O2 consumer brand was introduced on 19 June 2002 in the United Kingdom, Germany, Ireland and the Netherlands (where it lasted for only a year before reverting to Telfort). The rebranding was supported by a European advertising campaign, which began on 16 April 2002 across all four countries. Lambie-Nairn created the O2 brand identity.

Spanish telecommunications company Telefónica acquired O2 in the United Kingdom, Ireland and Germany in early 2006.

O2 and Virgin Media merged on 1 June 2021 creating Virgin Media O2, a 50/50 joint venture between Telefónica and Liberty Global.

However, O2 continues trading with this name as a subsidiary of Virgin Media O2.
