'The X Factor': The winner's auditions - video
Series One: Steve Brookstein
He first appeared on our screens grinning from ear-to-ear and appeared to forge a bond with Sharon Osbourne straight away. Eight years down the line, Brookstein is now found ranting on Twitter and don't even mention the words Shazza and Osbourne to him.
Series Two: Shayne Ward
Kate Thornton was still at the helm, we still only had three judges and Simon Cowell's hair was still very fluffy. Series two of The X Factor was a very innocent place and Shayne Ward's gleeful celebrations at passing his audition showcase that.
Series Three: Leona Lewis
She's still the most successful of all X Factor acts. Will anyone ever be able to surpass Leona? Oddly, her first audition wasn't particularly jaw-dropping. It was impressive, but her future mentor Simon Cowell noted a "fall off the melody". Keep your eyes peeled for a Paula Abdul guest spot as well.
Series Four: Leon Jackson
Bad hair. Dodgy sob story. Shaky vocals. It's no wonder Leon Jackson's career didn't smash up the charts. Would he even make it to Boot Camp these days?
Series Five: Alexandra Burke
After a rejection from Louis Walsh in a previous series, Alexandra came back better and stronger in series five. Even the smug look on Cowell's face as he pokes fun at Louis can't ruin this perfect audition. We also get the first appearance from Cheryl Cole on the show.
Series Six: Joe McElderry
Dodgy shirt, dodgy haircut... but voice of an angel. It also helped that he had some South Shields banter with Cheryl Cole to fall back on. A million mums across the country wept at Joe McElderry's 'Dance With My Father', which was the epitome of mass-appealing X Factor cheese.
Series Seven: Matt Cardle
"I'm a bit of a bum," admitted Matt Cardle before his first audition last year. Thankfully this negative attitude didn't translate into his zinger of a routine for the judges. His Amy Winehouse cover made him a favourite to win from the start.
The X Factor returns on Saturday at 8pm on ITV1.
