Trials of the UK's first HDTV service, the TVDrive PVR from Telewest, began on 1 December 2005 on a commercial pilot basis before a full launch in March 2006. Due to the merger between NTL and Telewest, the TVDrive was made available to NTL cable customers in the Teesside and Glasgow areas on 16 November 2006. In January 2007, NTL:Telewest began renting the STB nationwide and since the acquisition of the Virgin Media name, it is now officially available in all areas with the new V+ branding. Virgin Media is also the only cable provider to supply video on demand services.
