Nickelodeon lost a Japanese channel? Ouch. Perfect reason, then.
...I was just on that website, and it just surprised me, that's all.
Actually it originally was supposed to be a all-anime channel, but changed their standards sometime between 2008-2009.
Just last May, they completely changed the channel, and logo on Asia and Latin America (Germany will get this look in August, and evetually it'll be worldwide), to more of a variety network, and while Asia still airs mostly anime, Latin America...well...it;s pretty bad there.
