One of Britain’s biggest TV talent shows is going all Numa Numa. The X-Factor, an American Idol-like singing contest judged by Simon Cowell, will allow viewers to upload their own video performances to a website for viewing by fellow fans — and re-broadcast on the TV show. Producers Fremantle are already running a limited test on a similar show, Britain’s Got Talent. If executed well enough, this could give the growing army of bedroom lip-syncers and wannabe pop stars a way to participate in the show using webcams (Via NMA).
