The Voice set out to change the way we looked at singing competitions when it first launched in 2012.

With judges unable to see what each of their auditioners look like, there is no bias to image or style.

It solely goes down to the singing voice.

Swapping from BBC to ITV in 2017, the show is always changing judges, with will.i.am, Jennifer Hudson, Tom Jones and Olly Murs the latest batch of experts.
