A kids television channel that debuted in the 80s, hit it's prime in the 90s and then lost it completely.
The labelling of Nickelodeon as a kids channel is debateable because some of their best jokes and shows (before they went downhill) had enough depth to appeal to adults. Most notably, shows like
Ren & Stimpy, Rocko's Modern Life and the
late Invader Zim were filled to the brim with
quirky innuendo, jokes and/or references that will likely fly straight over a younger
child's head.
Since 2000, quality has been declining, and as of 2008 they have officially hit rock
bottom, essentially airing five or six substandard shows back-to-back, occasionally (though this
may not still be the case) showing some old programming during school hours so that older fans (now probably having left
school) can still find mild enjoyment in the channel.
It is hoped by many that Viacom is simply going through a rough
time and will pick up quality eventually, but as quality continues to decline, most older fans are giving up hope (which only makes sense given that it is a childrens channel).
