One of the best channels on
TV, until 2000/2001 when most of the classic and good shows were cancelled, thrust into reruns and replaced with mediocre shows, then around
2004 went downhill
even further when the classic shows weren't shown as reruns anymore, and the new new shows went from mediocre to just straight up crap.
Examples of the lost magic and current crapiness of Nickelodeon:
All That: Originally very funny and more mature, then became a dull kiddy show before it was cancelled.
The classic Rocko's Modern Life which was hilarious and
amazing has been replaced with the
annoying and repititive Spongebob Squarepants.
Even shows in the new generation of Nick which were actually cool
like My Life As A Teenage Robot, received good reviews and good ratings were cancelled. That seems to be a trend in Nick TV shows, cancel the good shows but keep the bullshit on.
