While the UK's fixed line internet infrastructure has been dominated by DSL (access technology that works on the standard telephone line network), cable broadband has proved popular in the regions that it is available. Cable broadband is provided by the cable television infrastructure, which was mostly built by two companies: 1) Telewest (previously named Croydon Cable, Blueyonder and Cable Internet); 2) NTL Incorporated (ntl) (previously named CableTel). NTL's cable infrastructure was powered by fibre optic cables and at its peak reached over 8 million premises in the UK. NTL's and Telewest's cable services did not massively overlap, and in 2006 the two companies merged; NTL's purchase of Telewest was one of the largest media company mergers in UK history. In February 2007 -- a year after merging with Virgin Mobile and after a failed merger with ITV -- NTL:Telewest was re-branded to Virgin Media. Virgin Media is currently the only major provider of cable broadband in the UK, and uses the Data Over Cable Service Interface Specification (DOCSIS) technology to provide the service. The NETGEAR CM1000 is an example of a modern cable modem that supports DOCSIS 3.0 and DOCSIS 3.1.
Virgin Media's cable network is mostly available in urban areas -- the majority of rural areas will not have access -- and some well known cable areas are: London, Bristol, Brighton, Portsmouth, Bournemouth, Exeter, Torquay, Plymouth, Cardiff, Swansea, Oxford, Swindon, Nottingham, Leicester, Norwich, Sheffield, Birmingham, Liverpool, Greater Manchester, Coventry, Derby, Lincoln, Grimsby, Leeds, Bradford, Middlesbrough, Newcastle upon Tyne, Sunderland, Edinburgh, Glasgow, Dundee, Cambridge and Chesterfield.
