Did you know that the famous Hatsune Miku song "Hatsune Miku no Shoushitsu -DEAD END-" (often translated to "The Disappearance of Hatsune Miku") was based off a real event?
Around October 2007, less than two months after Miku V2 first debuted, she vanished from Google and nearly every other online search engine, effectively wiping her from the internet for most. There are multiple possible reasons for this, with the most common explanation being that Miku simply blew up so huge and so quickly that most search engines flagged her name as spam. There's another belief that Miku's name was taken down due to actions by TBS (Japan) as a result of a controversial TV segment, which likened Vocaloid and Miku producers as no-life otaku.
Of course, I don't need to tell you that Miku was fine. She reappeared in search results the very next day. The now famous cosMo song would take inspiration from these events.
