+Pilun172:Icarly ended it was not cancelled the creators choose to end it because it has been on for a long time(7 Seasons so since 2007-2012) which is long enough for a show that starts in 2007 and ends in 2012.

Victorious was cancelled but that probably had to do with Victoria and Arianna Fighting.

Now with House of Anubis:Nina left in season 3 because her actress wanted to focus on school which would effect the shows ratings(which were originally high from seasons 1-2 but since Nina left and since her role was not recasted it gave the show low ratings) which Is one Reason why tv shows get cancelled,Low Ratings get shows Cancelled.
