Composers and Authors Society of Hong Kong Limited (CASH)
早於1946年，英國的演奏權益社(PRS)已在香港成立了一個機構，專責保護其會員和海外聯會的會員的音樂版權，為他們徵收演奏版權費。到了七零年代，樂迷對本地粵語歌曲的需求亦漸大，加上香港有著一群活躍和熱心的本地作曲家，他們非常樂意為他們的共同利益合作。在此種背景下， PRS 與這群香港作曲家在1977年達成協議，成立了香港作曲家及作詞家協會(CASH)。
In 1946, The Performing Rights Society (PRS) of the United Kingdom had set up an agency in Hong Kong to protect music copyright of its Members and Members of its overseas affiliated Societies. This agency conducted performing royalty collections. However, by the 1970's, there was a growing demand for local Cantonese music and there existed in Hong Kong an active and enthusiastic group of local composers who were ready and willing to cooperate for their mutual benefit. It was against this background that PRS arranged with this group of Hong Kong composers in 1977 to establish the Composers and Authors Society of Hong Kong Limited (CASH).
CASH was incorporated in Hong Kong on 23 September 1977 under the Companies Ordinance, being a Company limited by guarantee and not having a share capital. It started operating on 1 October 1977 and a press conference was held at the Mandarin Hotel to mark the establishment of CASH on 20 October 1977.
