The company was established in 1983 after successfully acquiring a local radio licence to broadcast Marcher Sound to Wrexham, Deeside and Chester on 95.4 MHz FM/VHF (from the Wrexham-Rhos Relay) and 1260 kHz AM/Mediumwave. The station launched on 5 September 1983. After a review, the frequency changed to the more familiar 103.4 MHz.
Due to IBA rulings, the company ceased simulcasting and started broadcasting different services on each frequency. The newer 103.4 FM frequency became MFM 103.4, the 97.1 FM frequency became MFM 97.1, and the 1260 AM frequency became Marcher Gold.
In 1999, MFM 97.1 was re-branded Buzz 97.1, and it moved from Moel-y-Parc to the Storeton transmitter, to specifically target listeners in The Wirral. At the same time, Marcher Coast FM was re-branded "Coast 96.3".
Recent re-brands have seen Buzz 97.1 become branded as "Wirral's Buzz", Champion FM 103 becoming simply "Champion", Coast 96.3 again becoming simply "Coast" and MFM 103.4 becoming Marcher Sound. In August 2007, 18 stations of the former Classic Gold Digital Network including Classic Gold Marcher were sold back to GCap Media, merging it with its own Capital Gold network. At this point Classic Gold Marcher was re-branded to simply "Wrexham and Chester Gold".
In 2000, the company was purchased by GWR Group, which included all of its radio assets. This followed an attempt to expand the Group further, including bidding for another licence on Merseyside, which was later secured by Dune FM. In 2005, GWR Group and Capital Radio merged to form GCap Media.
Upon purchase, Marcher's four FM licences became part of The One Network, a nationwide network of independent local radio stations operated by GCap Media which syndicate much of its programming from GWR FM, Bristol. The practice of programme simulcasting has been extensively used by Marcher in the past across its five FM stations, and still continues this to an extent in its local programming opt-outs.
