About o2

Although trading under the name of o2, the company is formally known as Telefonica UK and currently holds the title of the second largest telecommunications provider in the UK. Formed in 1985, o2 was not bought by Telefonica until 2006 but were taken over in a spectacular £18 billion deal, agreeing to keep the company’s headquarters in the Uk, as well as their original o2 brand. In 2016, there were talks of a controversial merger between major networks o2 and Three which was eventually blocked by the EU commissioner.
