1974年，無綫電視劇集《啼笑姻緣》首次使用粵語主題曲，被視為香港粵語流行曲發展嘅里程碑，標誌香港粵語流行曲再興起。劇集主題曲流行，令歌星亦得以多上電視節目，兩者相互推動，令本土音樂得以蓬勃發展。由1978年開始，獲得白金銷量嘅香港本地唱片數目，超越外國音樂唱片。
In 1974, the first Cantonese theme song was used in the cable TV drama "Laughing Marriage", which was regarded as a milestone in the development of Cantopop music in Hong Kong, marking the resurgence of Cantopop music in Hong Kong. The popularity of the theme song of the series has allowed singers to appear on more TV shows, and the two have boosted each other to thrive local music. Since 1978, the number of local recordings in Hong Kong has surpassed that of foreign music recordings.
