History
On 24 March 1998, the Radio Authority advertised for the first national ensemble to be broadcast on DAB, with the three Independent National Radio services on FM and medium wave required to be included in the ensemble - Classic FM, Talk Radio UK and Virgin Radio. The licence was awarded to the sole applicant, GWR Group and NTL Broadcast to form Digital One. The original licence application included the following stations:Digital One was due to launch on 1 October 1999, but this was postponed until 15 November 1999, when it started broadcasting at 1:00 pm. It was officially opened by Mel C.
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 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 ; 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 was launched as 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.
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.
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.
Former services
Services previously carried on the multiplex include:- Smooth Radio Christmas – festive music service, ran from 1 November until 27 December 2011 and operated again as a pop-up in Nov/Dec 2012, 2014 and 2015
- Absolute Radio 80s – 1980s music service. Transferred to the Sound Digital multiplex on 29 February 2016.
- Absolute Radio 90s – 1990s music service. Moved onto Digital One from 2010 – initially sharing a slot with Absolute Radio Extra – having previously been provided on local DAB; returned to local-layer DAB in January 2015 so that its capacity could go towards the addition of Magic to Digital One. Absolute Radio 90s returned to Digital One during 2018, before migrating across to Sound Digital in February 2019, as part of a wider reorganisation of Bauer's space across national and local DAB, ahead of the launch of Scala Radio on SDL in March.
- Planet Rock – Classic rock music station. Transferred to the Sound Digital multiplex on 29 February 2016.
- Smooth Radio – Easy listening service relaunched in 2010 as national network; local content on local/regional FM frequencies was replaced with network output also broadcast nationally on Digital One. New owners reintroduced local content on local FM/DAB in March 2014 and withdrew Smooth from Digital One in November 2014.
