I think if you look outside mainstream classical music you will see contemporary classicals influence. Many hollywood movie scores use many of the techniques created from serialism and onwards. Sampling audio with tape began in the 60s with Steve Reich, Pauline Oliveros at the San Francisco Tape Music Centre. You can see the influence in Hip Hop and Dance music. Synthesizers were originally only used by Academics making Contemporary Classical like Charles Wuorinen and Milton Babbit. They have obviously had a huge influence on pretty much all popular music. So even though the music itself has few fans its influence is fairly widespread.

That may be a case of simultaneous but unrelated discovery; audio sampling in hip-hop was an evolution of DJing techniques that helped to transition between or embellish songs, with beats or "get downs" being repeated to allow MCs to maintain a flow while rapping.
