Telewest, formerly Telewest Broadband and Telewest Communications, was a cable Internet, broadband internet, telephone supplier and cable television provider in the United Kingdom. It was listed on the London Stock Exchange and was once a constituent of the FTSE 100 Index.
In March 2006, Telewest merged with fellow cable telecom company NTL, and created 'NTL:Telewest', which then also merged with Virgin Mobile and Virgin.net in June 2006, creating the UK's first "quadruple play" telecom provider, offering television, internet, landline phone and mobile phone services. In February 2007, NTL:Telewest was rebranded as Virgin Media.
