The average audience for the first episode was 533,000, with the national broadcaster saying they were thrilled with its performance.
Presented by Grainne Seoige and running for 11 weeks, the first show saw Shane select five finalists from 500 entrants in the Dublin heats.
Drawing in a decidedly eclectic mixture of contestants, fame-seekers ranged in age from six years old right up to 90, all competing for the €50,000 prize.
There was no shortage of wannabes eager to step into the spotlight for their shot at fame, with plenty of tears and tantrums too.
Clearly one with a soft spot for the cutesy factor, viewers saw Shane ignore the advice of aides Evelyn O'Rourke and John Keogh when it came to the youngest entrant.
Despite the concerns of the other two panellists, he decided to put High School Musical performer Angela Mykolynk (6) forward as one of his final acts.
He also picked 13-year-old buskers Bert and Victor from Kilbarrack, alongside a young group of hip-hop dancers called Genesis.
