The anti-disco movement, combined with other societal and radio industry factors, changed the face of pop radio in the years following Disco Demolition Night. Starting in the 1980s, country music began a slow rise in American main pop charts. Emblematic of country music's rise to mainstream popularity was the commercially successful 1980 movie "Urban Cowboy". The continued popularity of power pop and the revival of oldies in the late 1970s was also related to disco's decline; the 1978 film "Grease" was emblematic of this trend. Coincidentally, the star of both films was John Travolta, who in 1977 had starred in "Saturday Night Fever", which remains one of the most iconic disco films of the era.
