What happened to the old Nickelodeon?

Nickelodeon used to be one of the greatest networks ever. It had shows like Doug, Rocko's Modern Life, Hey Arnold, Spongebob ( the older episodes), Ren & Stimpy, The Wild Thornberries, Kablam, Are you afraid of the dark?, The Angry Beavers, Rocket Power, Aaaah Real Monsters!, and other great shows. I miss those shows, but it's a different time now and different era so I'm, moving on. I will still watch these shows a lot. The shows today like Fanboy and Chum Chum sucks. The Mighty Bee sucks. Victorious sucks. I don't feel like going on with the rest of the sucky shows. Some shows like Jimmy Neutron, Action League Now: The Series, Invader Zim were really cool shows. I wish Nickelodeon created a channel dedicated to these good old shows. I know there's Nicktoons, but Nicktoons have the older cartoons on at like 2 in the morning. Who agrees with me?
