Grey Matters Productions Community Interest Company was set up by Brighton & Hove Council, Brighton & Hove Older People's Council, Brighton & Hove Pensioners' Forum and the local branch of Age Concern (now Age UK).

It's a non profit making organisation which makes radio programmes of general interest to the community but especially to older people. The programmes are broadcast on Brighton's Community Radio Station, RadioReverb, which can be heard on 97.2 FM in Brighton and Hove, on DAB+ Digital Radio, and on the Internet at www.radioreverb.com . Its programmes are also broadcast on Brighton's Hospital Radio Station, Coastway Radio.

Technical equipment was funded by a grant from the Lottery Fund Awards for All.
