So a lot of Creddie fans think that since iSaved Your Life was the record of the most amount of views for an iCarly episode (over 12 million views) it means that Creddie is the most popular shipping. Well, I would have to disagree with that...
I wasn't a Seddie shipper, or any shipper at all during this episode. But when I saw the promo, what stuck out to me was that a character on a kid's TV show gets hit by a taco truck trying to save his friends life. Who WOULDN'T wanna watch that!? Haha, just kidding. But the episode was something very different than what we usually see on iCarly.
Another factor could be that people wanted to see what would happen with Carly and Freddie kissing. I feel like all of the little kids who watch the show and don't know about the shipping think that Carly and Freddie will get together just because they seem perfect for each other. As I said before, I didn't know about Seddie or Creddie yet and during the ep. I decided that I really didn't like them together, I thought it was boring. And thus, a Seddie shipper was born. Lol.
So anyways, that's my opinion on it. I'm not trying to diss the episode, Creddie shippers, this is just why I think it was so popular.
