1) A popular children's television station, which became so in the 1990's with shows such as, but not limited to, "Ren and Stimpy," "Salute Your Shorts!," "Rocko's Modern Life," and "All That!". The station has since, however, decreased in popularity with its original viewers due to the cancellation of many of these shows.

2) An early motion-picture viewing "theatre," into which one would admit a nickel (hence the name) and be able to look into the invention and view a film.
I turned on the TV to find the station tuned to Nickelodeon.

He inserted five cents into the nickelodeon and watched a movie.

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).
Nickelodeon hardly needs an example now does it?

Network that was fan-freakin-tastic until around 1992/93 when the last of the good shows started to go. Tuned in once around 99 and the format sucked. MTVJr. I believe it's become now. What a f*cking waste of what was such a promising channel.
I turned on Nickelodeon the other day hoping to catch an episode of Salute Your Shorts, but all I got was this lousy Romeo.

A cable channel started by Warner Cable (the same company that invented MTV) in 1977 as "Pinwheel". The channel changed names to "Nickelodeon" in 1979 with unforgettable shows like "You Can't Do That On Television" which originated Nickelodeon's "sliming" trademark.

A great Kid's TV Channel until the mid-90's when it began to suck. It had supa-fly shows such as Clarissa Explains It All, The Adventures Of Pete and Pete, Doug, Salute Your Shorts, Ren and Stimpy, Rocko's Modern Life, Ahh! Real Monsters, Legends of the Hidden Temple, Figure it Out and etc. Then they started to slowly decline as they kept replacing the cast of All That, made a new version of Double Dare called Double Dare 2000. Their good cartoons were taken off the air and their ok cartoons such as Rugrats, got worse and worse. They occasionly had a good show like Invader Zim but was cancelled probably cuz faux-punks who shop at Hot Topic started wearing Gir and Zim pins and T-shirts. Now they just suck and show crappy shows such as ChalkZone, Fairly Oddparents, Zoey 101, and Unfabulous.

A station that once broadcasted legendery tv shows. Now it fails miserably. Viewers had hope for when it showed great programs such as Invader Zim and Avatar. But naturally, because everyone liked these shows, it became the number one priority of the network to cancel them as soon as possible forever.
Nickelodeon sucks!
Drake and Josh are funny on nickelodeon, not
Avatar was a great show, until Nickelodeon stopped showing new episodes for like a year.

A once respectable network now funneling in more crap than the Disney Channel
Mike: Do you wanna watch some Nickelodeon? I think iCarly is on.

Bill: I'd rather put meat hooks through my nostrils and attach them to a plane.
