What's even more amusing is that sentiment ("electronic music is now catching on") finds its way up every decade.
80s -> Disco & House -> Pop, New Wave
90s -> House -> Pop
00s -> Electro & DnB -> Pop, Hiphop
10s -> Dubstep -> Pop, Hiphop
That's just a crappy sketch but i'm sure someone could flesh it out further. The reality is that it's a continuum, things go in and out of style, what's popular changes, the audience changes, but the music never really goes away, we/you/i just don't know about it. Dubstep is simply the hair metal (80s), grunge (90s) of the times, not a statement about electronic music's popularity or unpopularity.
