The TV series "America or Busted", about Busted's attempts to achieve success in the United States, debuted on MTV UK and Ireland in November 2004. Over the course of the series, the audience see Busted's attempts to 'break' America dwindle as interviews fall through and performances remain limited both in terms of audience size and press attention.
After the failure of the US tour, rumours soon began to surface that a split was imminent. Simpson, who was currently in Fightstar (a post-hardcore band which differs greatly from the music Busted recorded) decided to leave Busted to concentrate on this band. Busted then formally disbanded at a press conference on 14 January 2005. Simpson recently stated that he left Busted because it was not the legacy he wanted to leave behind. Fightstar have since been the most successful of the three ex-Busted members, keeping consistency with singles and albums unlike Son of Dork and Matt Willis.
Bourne went on to release music through his punk band Son of Dork. 3 of 5 of the members have now left the band after reports that the band hadn't met up for months. There are reports that the band has disbanded for good, and Bourne is now pursuing a solo career after his performance in NYC.
Willis has also set up a solo career, having released his first single "Up All Night" in May 2006. Bourne and Willis are cited as still maintaining a friendship while it appears Simpson sees them very rarely. "Hey Kid" was Willis' next single release. The track is also the leading track on the soundtrack to American teen comedy drama John Tucker Must Die.It was also featured an the Stormbreaker soundtrack(American title:Alex Rider Operation Stormbreaker). Matt Willis released another track called "Don't Let It Go To Waste", several days after he was declared the winner of the 2006 series of I'm a Celebrity... Get Me Out of Here!. "Don't Let It Go To Waste" is also the name of his debut album. Matt Willis' fourth single "Crash" featured in the film Mr Bean's Holiday. Matt is currently presenting ITV 2's I'm a Celebrity Get Me Out of Here Now! alongside his girlfriend Emma Griffiths.
