On 24 March 1998, the Radio Authority advertised for the first national ensemble to be broadcast on DAB, with the three national commercial services on FM and medium wave required to be included in the ensemble. This included Classic FM, Talk Radio UK (now Talksport) and Virgin Radio (now Absolute Radio).[8] The licence was awarded to the sole applicant, GWR Group and NTL Broadcast to form Digital One.[9] The original licence application included the following stations:[10]

Digital One Ltd (original application)
Classic FM Classical music GWR (now part of Global Radio)
Classic Gold Rock Rock music NTL
Club dance Dance music TBA
Plays, books and music Comedy, drama and serials TBA
Rolling news service Rolling news ITN
Soft AC Female contemporary music TBA
Sports channel Live sports and comment Talk Radio UK
Talk Radio (now Talksport) Talk radio Talk Radio UK (now owned by Wireless Group)
Teen and chart hits Pop and dance music GWR
Virgin Radio (now Absolute Radio) Complementary rock music SMG plc (station is now owned by Bauer Media)

Digital One was due to launch on 1 October 1999,[11] but this was postponed until 15 November 1999.[12]

The "Classic Gold Rock" service eventually went on air as Planet Rock, which remains on air, having migrated from D1 to the Sound Digital multiplex in 2016; it is, however, the only one of the D1 launch stations (bar the INR simulcasts) still to be broadcasting as of 2017, and is also the longest-established DAB-first service in UK national radio, having been a digital-only service until 2013, when new owner Bauer put PR on their 105.2 FM frequency in the West Midlands (previously Kerrang! Radio); the FM berth was turned over to Absolute Radio in September 2015, leaving Planet Rock as a digital-only service once again. The "plays, books and music" service went on air as Oneword. The "Teen & Chart Hits" service became Core, and the "Soft AC" service – which was ultimately provided by the then Capital Radio Group (now part of Global Radio) was launched as Life (later known as Capital Life). The "Sports Channel" proposal was dropped as a separate entity and instead combined with Talk Radio in 2000 to form the current Talksport as broadcast on AM and DAB. ITN's rolling news service ultimately went on air as part of the multiplex, later joined by a business news service provided by Bloomberg. "Club Dance", however, never made it to air. The space released by the absence of the Club Dance and Sports Channel services from the eventual lineup was used to allow the Oneword service to end at midnight rather than the proposed 7pm, and also freed up a slot for a melodic easy-listening music service aimed at an older audience, the Saga-operated PrimeTime Radio.[citation needed]

After the closure of PrimeTime Radio in 2006, the original licence was amended to allow the launch of a new classic and contemporary jazz service, TheJazz which was launched on 25 December 2006, before 31 December 2006 deadline set in the licence amendment.[13]

On 11 February 2008 GCap announced that it was selling its interest in Digital One to Arqiva and that "non-core" DAB stations Planet Rock and TheJazz would be closing by the end of March 2008. Whilst TheJazz ceased broadcasting at midnight on 30 April 2008, Planet Rock was sold off and remains on air. GCap also closed down their two other D1-only stations, Core and Capital Life, prior to GCap being taken over later in 2008 by Global Radio.[citation needed]

Former services

Services previously carried on the multiplex include:

In addition to the audio services listed above a number of data services, short lived temporary audio services, and mobile video channels have been broadcast on this multiplex.


Main article: Birdsong (radio channel)

Birdsong was a temporary transmission of a continuously looping recording of bird song.[citation needed]

When the magazine-format digital radio station Oneword ceased in January 2008, the birdsong audio returned to the multiplex on the Oneword channel and the service name of the DAB channel changed to "Birdsong", until Amazing Radio launched on 1 June 2009.[19]
