I look at the NijiEN graphs because I am a faggot. I will not compare them to other graphs because I could do without getting ass blasted.
Typically, what you'd expect to see is a huge rush-in of attention at the start, and then a constant decline into flatline with maybe the odd bump every now and then if they release a banger song or secure some big collabs.
But look at these:
Not only growth, but unanimous, coordinated momentum across the board, to the point where members have recorded their best month three or even four times this year.
So while I can't determine if the audience is growing or if they're coming from existing fans who want a change of pace, I can say that there is at least a willingness to try new things and support other businesses, and that ebb and flow is quite healthy.
But also: shout-out to Nyanners for tanking her own channel by announcing she has a boyfriend. 5000 twitch subs lost.
