Säsongen 1 av iCarly sändes på Nickelodeon från samedi 8 septembre 2007 till vendredi 25 juillet 2008. Den består av 25 avsnitt, det första heter "iPilot" och det sista "iHave a Lovesick Teacher"..
Carly hosts her own home-grown web show, iCarly. She lives with her twenty-something brother/guardian Spencer and produces her Web casts from a makeshift third-floor loft studio. Grappling with adolescence, she never aimed to gain fame as a rising star/underground celebrity to kids. As events unfold in the pilot, it all happens by accident when a teacher puts her in charge of the school talent show. She and her sassy best bud Sam turn the audition process into a show, which Carly's tech savvy smitten friend Freddy tapes -- including their hilarious banter and great chemistry -- and posts on the Web without telling the girls. The on-line audience clamors for more, and a pop phenomenon blooms, with Carly and sidekick Sam's regular Web casts ultimately featuring everything from comedy sketches and talent contests to interviews, recipes, and problem-solving.
