Marketing is certianly the easy answer simply for the notable lack of. Of course marketing isn't always the answer, MAYU being a fine example as she received an alright reaction at most but now she's even been shoved out the spotlight on EXIT TUNES "Vocalo" Album series.

Even so, I would say that "then" wouldn't be so invalid if it weren't for the fact that "then" was sheer luck, not to mention that what companies have done similar to "then" hasn't worked. (E.g. Being moe and aiming for Otaku's specifically did nothing sadly for Tone Rion despite being better quality than Miku, personally at least for the later comment). It's only really worth noting for the sake of noting it.
