The episode is not all about Miku however, so don't get the wrong idea please.
It's actually heavily focused on Hello Kitty. (Miku part starts at around 20 min.)
Anyway, this episode of Japanology was relevant to Japanese subculture, so I'm uploading the torrent.
Although this is a raw video, no subs are needed, since the original broadcast has
English narration and voiceovers.
