Top 10 Classic Nickelodeon Shows

Only one can be number one. SpongeBob SquarePants is not only Nickelodeon's most successful series, but also a global cultural phenomenon. The adventures of the always optimistic sponge in Bikini Bottom are now legendary. Whether you like Patrick, Squidward or Mr. Krabs, SpongeBob remains the undisputed king of the Nickelodeon era.

This is considered by many to be one of the best animated series ever made. The story of Aang, the last Airbender who had to master the four elements to save the world, was epic and profound. The character development and world building in Avatar were at a level rarely seen in children's series.

iCarly was ahead of its time by creating a series about a girl who started her own web show. Carly, Sam and Freddie became internet stars from an attic room. The series mixed internet culture with typical Nickelodeon humor and was one of the channel's most-watched live-action shows.

Timmy Turner didn't have an easy time with his mean babysitter Vicky, but luckily he had Cosmo and Wanda: his fairy godparents. With their help, he could make any wish come true, which usually resulted in total chaos.

Drake & Josh showed how two completely different stepbrothers were forced to live together. Drake was the cool musician and Josh the neurotic perfectionist. The series was a huge hit thanks to the quick wit and constant bullying of their younger sister Megan, played by Miranda Cosgrove.

Nickelodeon was known for its bizarre concepts, and CatDog was the ultimate example of that. Siamese twins consisting of a dog and a cat attached to each other caused constant fighting. The refined Cat and the impulsive Dog always had to work together despite their opposite characters, which led to the strangest situations.

Who hasn't dreamed of attending a boarding school like Pacific Coast Academy (PCA) in the past? Zoey 101 followed Zoey Brooks and her group of friends on this beautiful campus on the coast. The series was extremely popular because of the recognizable teenage adventures, the cool gadgets (such as the TekMate) and of course the first puppy loves.

Hey Arnold! was much more mature than most animated series of the time. The series followed the optimistic Arnold, who lived with his grandparents in a boarding house. The show tackled deeper themes such as loneliness, friendship and love (think secret admirer Helga Pataki), all set against the backdrop of an atmospheric big city.

“Who loves orange soda? Kel loves orange soda!” This legendary sitcom revolved around the friendship between the enterprising Kenan and the clumsy Kel. The chemistry between the duo was golden, and their absurd plans usually went completely out of hand, much to the frustration of Kenan's parents and his boss at Rigby's.

Rugrats was one of Nickelodeon's first big hits. The series gave us a unique glimpse into the world through the eyes of babies like Tommy, Chuckie and the evil Angelica. What made the show so strong was that the babies turned everyday situations into epic adventures, purely through their enormous imagination.
