when did the millennium dome became the o2 arena
Millennium Dome The dome was publicly renamed as The O2 on 31 May 2005, in a £6 million-per-year deal with telecommunications company O2 plc, now a subsidiary of Telefónica Europe. This announcement, which presaged a major redevelopment of the site that retained little beyond the shell of the dome, gave publicity to the dome's transition into an entertainment district including an indoor arena, a music club, a cinema, an exhibition space and bars and restaurants. This redevelopment was undertaken by the dome's new owners, the Anschutz Entertainment Group, to a design by HOK SVE and Buro Happold. It cost £600 million, and the resulting venue opened to the public on 24 June 2007, with a concert by rock band Bon Jovi.[30]
