Well, as the years go by, Nick will lose more popular shows, and Teen Nick. Pretty soon all that's going to be left is Nick Jr and SB and Avatar. SB and Avatar are going to go to Cartoon Network, and Nickelodeon will change to 24/7 Nick Jr. like Noggin or something. Then those popular shows will die out, and the remaining ones will go to Noggin, and Nick will end.
Very fascinating, isn't it?
