The new presenting team would take turns hosting (initially usually in pairs but sometimes solo), and would often introduce acts in an out-of-vision voiceover over the song's instrumental introduction. They would sometimes even conduct short informal interviews with the performers, and initially the Top 10 countdown was run without any voiceover. Rules relating to performance were also altered meaning acts had to sing live as opposed to the backing tracks for instruments and mimed vocals for which the show was known. To incorporate the shift of dominance towards American artists, more use was made of out-of-studio performances, with acts in America able to transmit their song to the "Top of the Pops" audience "via satellite". These changes were widely unpopular and much of the presenting team were axed within a year, leaving the show hosted solely by Dortie and Franklin (apart from the Christmas Day editions, when both presenters appeared) from October 1992, on a week-by-week rotation.
