principles of taking responsibility for bettering the lives of the workers, pioneered in their Bournville operation in the United Kingdom. Architects James Earle and Bernard Walker sought to provide an all-round community, and created the Cadbury Estate alongside the factory, where the workers were provided with comfortable housing, shops, entertainment and sporting facilities, designed to engender a sense of community and personal well-being amongst Cadbury's workers. The local economy of Hobart has continued to survive on primary industries such as agriculture and fishing, and smaller scale industries such as canneries, fruit processing works, furniture manufacture, silk and textile printing, soft drink and confectionery production. Cottage industries such as pottery, woodwork, crafts and textiles also persist. The first radio broadcast in Tasmania was on 17 December 1924 in Hobart. The development had come as part of a Commonwealth Government initiative earlier in 1924 to develop top quality radio broadcasting facilities in each state capital. The projects were funded by licensing fees, limiting those permitted to receive the broadcasts, but by mid-1925, 526 people in Hobart had bought licences to listen to broadcasts. The first Hobart station, 7ZL, was established by the Associated Radio Company, which was later bought by Tasmanian Broadcaster Pty Ltd in 1928. Finally, in 1932, ownership transferred to the Commonwealth Government owned Australian Broadcasting Commission as a result of an act of the Commonwealth Parliament nationalising radio companies. The transfer of ownership which brought free broadcasting to Hobart for the first time, was in time for Hobart listeners to receive news that the first Tasmanian born Prime Minister, Joseph Lyons had been appointed. 7ZL was broadcast on the 580 AM frequency with a one-kilowatt transmitter. By 1937 the Hobart audience had grown sufficiently to warrant a second station, and in that year the Post-Master General announced that 7ZR would begin transmitting on the 1160 AM frequency. The following year, Hobart listeners tuned into 7ZR to hear Don Bradman score 144 in a tour match against the Tasmanians at the TCA Ground. Since its inception, 7ZR has since remained with the ABC and now forms part of the ABC Local Radio network as ABC Radio Hobart. During the 1930s, the Modern movement of architecture became quite popular in Hobart, and although few examples survive, one such example is the Sunray Flats (1938) in Davey Street. Designed by Colin Philp of Hartley Wilson and Philp, they are an example of
