O2 (Ireland) fixed line and mobile services are branded as movistar. In January 2009, it was revealed that Ireland was nearly the most profitable market in the world for multinational mobile operators like O2. On 23 March 2009 Vodafone and O2's parent company Telefónica announced a deal to share their existing networks in Ireland and rollout future infrastructure jointly. On 6 April 2011 it was announced that Telefónica O2 Ireland and Eircom had agreed a new network sharing partnership. On 24 June 2013, it was announced that Hutchison Whampoa would acquire Telefónica's Irish mobile operations for €780 million, to be merged into
The O2 in 2006. As part of the investment programme, naming rights were sold to O2 plc, and 'The O2' became the official name of the project on 25 May 2005. The £6 million per year deal between O2 plc and AEG included priority tickets and reserved VIP accommodation for O2 mobile customers. The service was also made available to premium ticket holders. O2 plc started talks with AEG in 2005 to have its logo and branding placed on the roof of the dome, but this did not take place. AEG have constantly stated that they wish to abolish the 'Dome' name
