VJing originated in 1970s New York club culture, predating MTV's adoption of the term

The term ‘VJ’ arose in the New York club scene of the late 1970s, before MTV adopted it for its Video Jockeys in 1981; the article notes VJing became popular via MTV ‘but its origins date back to the New York club scene of the 1970s.’ Merrill Aldighieri is documented as the world’s first full-time VJ, mixing a body of ambient visuals live alongside a DJ at the nightclub Hurrah around 1980. MTV’s founders visited that club and she introduced them to the term and the role of ‘VJ’. The common error is to treat MTV as the origin of VJing; MTV popularized the label but inherited a pre-existing club practice.

Examples

Merrill Aldighieri’s 1980 Hurrah sets: she made a large body of ambient visuals combined in real time to interpret the DJ’s music, becoming the world’s first full-time VJ — a year before MTV launched its VJ hosts.

Assessment

Explain why MTV is commonly but wrongly credited as the origin of VJing. Cite the club and the person the article identifies as the first full-time VJ, and state roughly when.
