 After relocating to the UK in the mid-1970s, Mulcahy made successful promo films for several noted British pop acts—his early UK credits included XTC's "Making Plans for Nigel" (1979) and his landmark video clip for The Buggles' "Video Killed the Radio Star" (1979), which became the first music video played on MTV in 1981.In 1975, the British rock band Queen employed Bruce Gowers to make a promotional video to show their new single "Bohemian Rhapsody" on the BBC music series "Top of the Pops".According to rock historian Paul Fowles, the song is "widely credited as the first global hit single for which an accompanying video was central to the marketing strategy".
