By 1988, there were 69 local commercial stations, each broadcasting on both MW (AM) and VHF (FM). In that year, the Government permitted local commercial stations to offer different services on their MW and VHF frequencies. Following this liberalisation, a number of different formats were experimented with on MW by the commercial radio companies, but by far the most commonly adopted was the ‘Gold’ format, majoring on chart hits from the 1960s and 70s. The overall number of stations increased dramatically as a result.
In 1990, the IBA began to award licences for stations in areas already served by an existing commercial station. The aim was to increase the range of programming available to listeners. Early examples included Jazz FM and Kiss in London, designed to appeal to a different audience from Capital or LBC.
In 1991, the Radio Authority replaced the IBA as the commercial radio regulator and followed a policy of licensing stations to fill in the gaps in existing coverage, to offer smaller stations in areas already covered by large commercial stations and to offer regional stations, which could extend the range of programming available to audiences
The general trend in regulation of commercial radio has been gradually to lessen the regulatory burden on radio stations as the competition for revenues and the choice for listeners increases.
Since then, commercial operators have also made significant investments in digital radio. A national commercial multiplex licence was awarded to Digital One in 1998. Digital One launched its first national commercial services in 1999 and now offers eight services, including five available only on digital. Local DAB commercial services are now available from 46 local DAB digital radio multiplexes around the UK. Digital versions of the relevant BBC Local Radio or nations’ services are also carried on the appropriate local commercial multiplex.
