NTL Incorporated  NTL Incorporated, branded as ntl:, was a United States-listed British company founded in 1992, which provided cable television, cable internet and fixed-line cable telephone services. While NTL had its headquarters in New York City, the company's activities focused heavily on the United Kingdom, with operational headquarters in Hook, Hampshire. NTL became the dominant cable operator in the United Kingdom, controlling more than 90% of the market. In 2005 residential services generated 78% of NTL's revenue, and business services 22%. In March 2006, NTL merged with fellow cable telecom company Telewest, and created 'NTL:Telewest', which then also merged with Virgin Mobile UK 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. Barclay Knapp and George Blumenthal, the founders of American cellular network company Cellular Communications, Inc. (sold to Airtouch in 1996), established International CableTel in 1993 to take advantage of the deregulation of the UK cable market. Initially, Cabletel acquired local cable franchises covering Guildford and parts of Northern Ireland, Scotland and Wales. In 1996 CableTel acquired National Transcommunications Limited (NTL), the privatised UK Independent Broadcasting Authority transmission-network. In May 1998 CableTel adopted "NTL" as its new name. The company spent heavily: both on expanding its network and on acquiring rivals (in 1999, it acquired Cambridge Cable, one of the earliest digital networks, that had been installed across the university city ten years earlier). The company also began to expand outside the UK in 2000, buying into markets on continental Europe and Ireland. A collapse of the telecommunications markets from mid-2000 dealt a serious blow to the company. This, combined with NTL's rapid acquisition of local cable-operators, led to severe integration problems. NTL, struggling to cope with rapid expansion and suffering from significant customer-service problems, then had to contend with the setting up in November 2002 of one of the UK's first consumer lobby-groups, nthellworld, with ntl:hell following shortly after. As a complementary move, a team of NTL employees founded the website, Chetnet.co.uk, to provide customers with a site focused on providing expert advice on its subject-matter, based on factual information, without the emotion or speculation of the "lobby groups".
