Here's why:
* Dan Schneider had a history of creating successful shows for kids before iCarly. He was already well-known for shows like "All That" and "Drake & Josh," showcasing his ability to understand what resonated with young audiences.
* Miranda Cosgrove was chosen for the role of Carly through a casting process. She was one of many talented young actresses who auditioned for the part.
* The show's concept and characters were developed before casting. iCarly was about a group of friends who made web shows, not specifically focused on one individual.
While it's true that Miranda Cosgrove's performance as Carly was a significant part of the show's success, Dan Schneider created iCarly with a broader vision in mind, targeting a wide audience of kids and teenagers.
