Nickelodeon...really?

Growing up I used to love the shows Nickelodeon provided. There was a ton of variety and the majority of them appealed to me. I am wondering what has happened to the network. Why are there only 2 or 3 shows that are on the network these days? Is Nick still making as much money as it once did or is it plummeting out of the Viacom world? Nickelodeon no longer even provides cartoons besides Songebob. Part of the appeal that I used to have with Nickelodeon was that it had a nice mix of cartoons and shows with real characters. The shows with real people varied from game shows to The Weird World of Alex Mac. It's hard for me to have grown up with these shows and not to have access to them now. It's like they were erased from my past because I can't even find them online. I am wondering what the network of Nickelodeon is thinking? Why have they changed it so drastically from what it used to be? I believe that children would enjoy Hey Arnold, Rugrats, Ahh Real Monsters, and the other shows that used to be offered if still available. I am frankly upset and disgusted with the options that are currently on the network. Who is making all of the decisions? I realize we are living in a new time then we were 10 years ago but I am still appalled with the options that are left for the children these days. They have no variety and it's no way to grow up!
