ABC Radio and Regional Content, later ABC Radio, was the division of the Australian Broadcasting Corporation responsible for radio output and regional content. Origins The first public radio station in Australia opened in Sydney at 8:00pm on 23 November 1923 under the call sign 2SB. Other stations in Melbourne, Brisbane, Adelaide, Perth and Hobart followed. A licensing scheme administered by the Postmaster-General's Department, was soon established allowing certain stations government funding, albeit with restrictions placed on their advertising content. In 1924 the licensing system was changed. The Postmaster-General's Department collected all licence fees and broadcasters were funded as either A-Class or B-Class stations. A-Class stations received government funding and were able to take limited advertising, while B-Class stations received no government funding but could carry more advertising. By 1925 many of the A-Class stations were in financial difficulty. A 1927 Royal Commission into wireless broadcasting recommended that radio licence fees be pooled to fund larger A-Class stations. The government established the National Broadcasting Service to take over the 12 A-Class licences as they came up for renewal from 1928. The original legislation permitted advertising, but this was removed from the Act before it came into effect. At the same time, the government created the Australian Broadcasting Company to supply programs to the new national broadcaster. Initially the Postmaster-General's Department, which operated postal and telephone services, was responsible for operating the National Broadcasting Service, although this arrangement did not have universal political support. As a result, the Australian Broadcasting Commission was established on 1 July 1932 to take over the Australian Broadcasting Company and run the National Broadcasting Service. The ABC was to be based on the BBC model, funded primarily through listener license fees, with some direct government grants. The Australian Broadcasting Commission's original twelve radio stations were: 2FC Sydney 2BL Sydney 3AR Melbourne 3LO Melbourne 4QG Brisbane 5CL Adelaide 6WF Perth 7ZL Hobart 2NC Newcastle 2CO Corowa 4RK Rockhampton 5CK Crystal Brook These formed the basis for the present-day ABC Local Radio and Radio National networks. The opening-day program included the first ‘Children's Session’ with ‘Bobby Bluegum’; the first sports program, ‘Racing Notes’, with WA Ferry calling the Randwick races; ‘British Wireless News’, received by cable from London; weather; stock exchange and shipping news; the ABC Women's Association session (on ‘commonsense housekeeping’ and needlecraft); a talk on goldfish and their care; as well as ‘Morning Devotions’ and music.
