Hit 105 (call sign: 4BBB) is a commercial FM radio station broadcasting on 105.3 MHz in Brisbane, Australia. It is part of Southern Cross Austereo's Hit Network. Hit 105's primary audience is 10 to 24 age group. The station was previously branded as B-105 FM following its conversion from AM to FM. This lasted until a co-branding as "Hit 105.3 B 105", then as "Hit B 105" and finally dropped the "B" reference to its present brand identity "hit 105". The B had referred to Brisbane. The station shares branding with SCA's Perth (hit 92.9) and Adelaide (hit 107) stations. ==History== The station now known as Hit 105 began life as 4BK, commencing transmission on 1930 on the AM band, initially on the frequency 1290 kHz before changing to 1300 kHz on 1 Sep 1935 (to accord with the new Australian 10 kHz channel spacing raster). Again the implementation by Australia of the 9 kHz channel spacing raster developed by the ITU and formalised in the 1975 Geneva Plan necessitated 4BK moving to 1296 kHz on 23 November 1978. In 1988, the Austereo group purchased the station from Hoyts, intending to use it as a vehicle to bid for an FM conversion licence. Austereo won the FM licence, and in February 1990, the station changed its callsign to 4BBB (not used on-air except during test broadcasts, unlike the previous AM callsign) and commenced broadcasting on a frequency of 105.3 MHz with the on-air name B105. Between March 1990 until 2006 it was the highest rating station in Brisbane, except in one ratings survey in 1994, beaten by AM station 4KQ. In April 2011 the Austereo Group was purchased by Southern Cross Media for more than $700 million, and is now operated under the name Southern Cross Austereo. On Friday 6 March 2015, B105 rebranded as Hit 105.〔http://www.radiotoday.com.au/news/whats-new/6456-hit105-arrives.html〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HIT 105」の詳細全文を読む スポンサード リンク
