Telling the SpongeBob story feels like the perfect fit ."

It held an average national Nielsen rating of 4.9 among children aged two through eleven, denoting 1.9 million viewers . Two years later, the series had firmly established itself as Nickelodeon's second highest rated children's program, after Rugrats . That year, 2001, SpongeBob SquarePants was credited with helping Nickelodeon take the "Saturday - morning ratings crown" for the fourth straight season . The series had gained a significant adult audience by that point--nearly 40 percent of its 2.2 million viewers were aged 18 to 34 . In response to this weekend - found success, Nickelodeon gave SpongeBob SquarePants time slots at 6 PM and 8 PM, Monday through Thursday, to increase exposure of the series .

Nickelodeon "recognized" The Fairly OddParents for its climbing ratings and installed it into a new 8 P.M. time slot, previously occupied by SpongeBob SquarePants . In an interview, Cyma Zarghami, then - general manager and executive vice president of Nickelodeon, said, "Are we banking on the fact that Fairly OddParents will be the next SpongeBob?...We are hoping . But SpongeBob is so unique, it's hard to say if it will ever be repeated". </P>
