Many were originally set up as a 'Gold' counterpart (e.g. Radio City Gold in Liverpool) when stations were instructed by the Independent Broadcasting Authority to cease simulcasting their services on both AM and FM in the late 1980s.

In Scotland, local programming on AM stations was largely retained until networking outside of weekday breakfast and specialist shows was introduced in June 2009.

[12] Most of the stations were merged and began carrying networked output, alongside a regional show on weekdays and localised news, travel and advertising.

The nineteen stations carried local breakfast shows and voicetracked programming whilst retaining separate branding until the full relaunch on 1 September 2020.

[15] On 15 October 2020, it was announced that the Suffolk station Ipswich 102, part-owned by Bauer through their purchase of Lincs FM Group, would take the GHR brand and network programming, including the East region drivetime show, from November, with the former Town 102 on DAB, which had carried GHR East since the September network relaunch, being replaced by Hits Radio.

[20] On 22 November 2022, Bauer announced that CFM in Cumbria & South West Scotland will rebrand to Greatest Hits Radio from 3 April 2023.

[21] On 12 January 2023, Bauer announced that the seven heritage names in Scotland (Clyde 2, Forth 2, MFR 2, Tay 2 and Westsound (Ayrshire) and (Dumfries and Galloway), would rebrand as Greatest Hits Radio from 3 April.

[24] On the same day, Bauer also announced that three of the four FM frequencies held by Kiss in Cambridge (105.6), Ipswich and Colchester (106.4) and Peterborough (107.7), would switch to carrying Greatest Hits Radio and join the GHR East network.

[25] On 12 November 2023, it was announced that GHR's remaining medium wave transmissions, in Scotland and northern England, would cease by the end of the year, but the station would continue on DAB in the affected areas.

[32] Bauer's newsrooms across the UK air mixed local and national news bulletins hourly from 6am to 7pm on weekdays and from 7am to 1pm on Saturdays and Sundays.

At weekends, bespoke networked news bulletins air during the afternoon produced by the Bauer newsroom in Glasgow for Scotland and usually either Leeds or Manchester for England and Wales.

At all other times, mainly evening and overnight, hourly national bulletins originate from Sky News Radio.
