Glad I stopped watching Nickelodeon after 1991. You Can't Do That On Television, Double Dare, Hey Dude, and Clarissa Explains It All. That's where it was at. And they had a cartoon called Count Duckula. Also Nick At Nite with old shows from the '50s and '60s. They even made their own original sitcom called Hi Honey, I'm Home with a '90s family living next door to a '50s sitcom family. Hilarity ensued.
Good times.
EDIT: I remember them showing TAS on Nickelodeon too.
I think Nickelodeon has changed a lot since 1991. Now I live in Canada and I got most of the Nickelodeon content from a channel called YTV. But I like animation (not as much as I used to) kinda stay knowledgable of stuff going on with animation in general.
There were some interesting videoes about Nickelodeon's rise and fall, you do not have to watch them, but I think are interesting.
I think after 1991, Nickelodeon had a big heyday from the 1990s to early 2010s, but have fallen off in the last decade. But I do think Viacom has realized that and is trying to right the ship:

In 2005 Nickelodeon made the best cartoon they have ever had, Avatar the Last Airbender, an epic fantasy series with an anime like style that has real stakes, likable heroes, menacing villains, morally gray characters, etc which changed things up as much as Batman TAS did in the 90s. If the new Star Trek cartoon is even close to being as good as Avatar the Last Airbender, you would have a lot of new Star Trek fans right away. Avatar the Last Airbender is the thing that is closest to Star Trek that Nickelodeon has made.
However, I think this Star Trek cartoon might want to take some notes from the Star Wars Clone Wars cartoon, that cartoon was able to take the mostly off-screen Clone Wars and expand upon it in animation, that show took what works for the movies and made it work in animation.
I think kids animation has changed a lot in recent times, stuff you would never see in the past in kids animation in the past (LGBT representation) is more common now. I think Star Trek can make its mark in animation better now than in the 1970s, there is more competition, but its easier to tell great Star Trek stories in kids animation now than in the past.
